faa13539d5 wallet: Fix documentation around WalletParameterInteraction (MarcoFalke)
Pull request description:
Comes with a test to aid review. The test should fail without the fix to bitcoind
The following `CreateWalletFromFile` issues are fixed:
* `walletFile` refers to freed memory and will thus corrupt the debug.log and/or crash the node if read
* `WalletParameterInteraction` was moved to `CreateWalletFromFile` and `WalletInit::ParameterInteraction` without updating the documentation

Pull request description:
Transaction relay is optimized for a combination of redundancy/robustness as well as bandwidth minimization -- as a result transaction relay leaks information that adversaries can use to infer the network topology.
Network topology is better kept private for (at least) two reasons:
(a) Knowledge of the network graph can make it easier to find the source IP of a given transaction.
(b) Knowledge of the network graph could be used to split a target node or nodes from the honest network (eg by knowing which peers to attack in order to achieve a network split).
We can eliminate the risks of (b) by separating block relay from transaction relay; inferring network connectivity from the relay of blocks/block headers is much more expensive for an adversary.
After this commit, bitcoind will make 2 additional outbound connections that are only used for block relay. (In the future, we might consider rotating our transaction-relay peers to help limit the effects of (a).)

Translated strings should not end up in the debug log, stderr, or
returned by an RPC.
Changing the util methods in util/error to return a bilingual_str paves
the way to achieve this goal in the long term.

CSV and segwit have been active for over 18 months. Hardcoding the activation height is a code simplification, makes it easier to understand segwit activation status, and reduces technical debt.

This change encapsulates UTXO set data within CChainState instances, removing
global data `pcoinsTip` and `pcoinsviewdb`. This is necessary if we want to
maintain multiple chainstates with their own rendering of the UTXO set.
We introduce a class CoinsViews which consolidates the construction of a
CCoins* hierarchy. Construction of its various pieces (db, coinscatcher,
in-memory cache) is split up so that we avoid flushing bad state to disk if
startup is interrupted.
We also introduce `CChainState::CanFlushToDisk()` which tells us when it is
safe to flush the chainstate based on this partial construction.
This commit could be broken into smaller pieces, but it would require more
ephemeral diffs to, e.g., temporarily change CCoinsViewDB's constructor
invocations.
Other changes:
- A parameter has been added to the CCoinsViewDB constructor that allows the
name of the corresponding leveldb directory to be specified.
Thanks to Russell Yanofsky and Marco Falke for helpful feedback.

Under an assumeutxo model, we have multiple CChainState instances in use at once in order to support background validation. Currently, each CChainState instance has its own mapBlockIndex, a collection of linked block headers, in addition to a few other data structures that are related to maintenance of the block tree but not necessarily to any given chainstate.
In order to avoid duplicating this data across chainstates, this change moves chainstate-agnostic block metadata (and related behavior) into a class, `BlockManager`. Chainstates are parameterized with a reference to a blockmanager instance and in practice they share the same instance.
Most of this change is conceptually move-only, though the diff is somewhat muddled. The first commit can be reviewed slightly more easily with `--color-moved=dimmed_zebra`. Admittedly, that commit is pretty unwieldy; I tried to split it up after the fact with `git add --patch`, but that was difficult because of git's inability to split hunks past a certain point. Some of the moves also ended up being obscured when done over separate commits.

At this point there is no reasonable excuse to disable opt-in RBF,

This removes an option that is:

* (b) is detrimental to everyone (income for miners, RBF notifications for others) who uses it individually otherwise
* (c) is effectively unused

Make reasoning about dependencies easier by not including unused dependencies.
Please note that the removed headers are _not_ "transitively included" by other still included headers. Thus the removals are real.
As an added bonus this change means less work for the preprocessor/compiler. At least 51 393 lines of code no longer needs to be processed:
```
$ git diff -u HEAD~1 | grep -E '^\-#include ' | cut -f2 -d"<" | cut -f1 -d">" | \
sed 's%^%src/%g' | xargs cat | wc -l
51393
```
Note that 51 393 is the lower bound: the real number is likely much higher when taking into account transitively included headers :-)

This changeset starts moving functionality intimately related to CChainState into methods. Parameterizing these functions by a particular CChainState is necessary for the use of multiple chainstates simultaneously (e.g. for asynchronous background validation).
In this change, we
- make the CChainState interface public - since other units will start to invoke its methods directly,
- introduce `::ChainstateActive()`, the CChainState equivalent for `::ChainActive()`,
- and move `IsInitialBlockDownload()` and `FlushStateToDisk()` into methods on CChainState.
Independent of assumeutxo, these changes better encapsulate chainstate behavior and allow easier use from a testing context.
There are more methods that we'll move in the future, but they require other substantial changes (i.e. moving ownership of the `CCoinsView*` hierarchy into CChainState) so we'll save them for future PRs.

ccc27bdcd2 doc: Clarify -blocksdir usage (Daniel McNally)
Pull request description:
This PR attempts to clarify and correct the `-blocksdir` argument description and default value. `-blocksdir` does not refer to the full path to the actual `blocks` directory, but rather the root/parent directory which contains the `blocks` directory. Accordingly, the default value is `<datadir>` and not `<datadir>/blocks` - this behavior of defaulting to the datadir can also be seen in init.cpp:
```cpp
if (gArgs.IsArgSet("-blocksdir")) {
path = fs::system_complete(gArgs.GetArg("-blocksdir", ""));
if (!fs::is_directory(path)) {
path = "";
return path;
}
} else {
path = GetDataDir(false);
}
```
It also attempts to clarify that only the `.dat` files containing block data are impacted by `-blocksdir`, not the index files.
I believe this would close#12828.

This work is prerequisite to attaching thread names to log lines and deadlock
debug utilities. This code allows setting of an "internal" threadname per
thread on platforms where thread_local is available.
This commit also moves RenameThread() out of a more general module and adds a
numeric suffix to disambiguate between threads with the same name. It
explicitly names a few main threads using the new util::ThreadRename().

418d3230f8 Resolve the checkpoints <-> validation CD. (251)
Pull request description:
This pull request attempts to resolve the `checkpoints -> validation -> checkpoints` circular dependency.
The circular dependency is resolved by moving the `CheckPoints::GetLastCheckpoint(const CCheckpointData& data)` function to `validation.cpp` where it used exclusively by the private function `ContextualCheckBlockHeader(const CBlockHeader& block, CValidationState& state, const CChainParams& params, const CBlockIndex* pindexPrev, int64_t nAdjustedTime)`.

Pull request description:
This introduces a new BlockFilterIndex class, which is required for BIP 157 support.
The index is uses the asynchronous BaseIndex infrastructure driven by the ValidationInterface callbacks. Filters are stored sequentially in flat files and the disk location of each filter is indexed in LevelDB along with the filter hash and header. The index is designed to ensure persistence of filters reorganized out of the main chain to simplify the BIP 157 net implementation.
Stats (block height = 565500):
- Syncing the index from scratch takes 45m
- Total index size is 3.8 GiB

Pull request description:
This is a move-only commit. No code is changing and the moves can be easily verified with:
```sh
git log -p -n1 --color-moved=dimmed_zebra
```
This commit moves functions and variables that wallet code depends on out of libbitcoin_server.a, so the bitcoin-wallet tool can be built without libbitcoin_server.a in #15639, and attempting to access server state from wallet code will result in link errors instead of silently broken code.
List of moves:
- `CheckTransaction` moves from `consensus/tx_verify.cpp` to `consensus/tx_check.cpp`
- `urlDecode` moves from `httpserver.cpp` to `util/url.cpp`
- `TransactionErrorString` moves from `node/transaction.cpp` to `util/error.cpp`
- `StringForFeeReason` and `FeeModeFromString` move from `policy/fees.cpp` to `util/fees.cpp`
- `incrementalRelayFee` `dustRelayFee` and `nBytesPerSigOp` move from `policy/policy.cpp` to `policy/settings.cpp`
- `SignalsOptInRBF` moves from `policy/rbf.cpp` to `util/rbf.cpp`
- `fIsBareMultisigStd` moves from `validation.cpp` to `policy/settings.cpp`
- `ConstructTransaction` `TxInErrorToJSON` and `SignTransaction` move from `rpc/rawtransaction.cpp` to `rpc/rawtransaction_util.cpp`
- `RPCTypeCheck` `RPCTypeCheckArgument` `RPCTypeCheckObj` `AmountFromValue` `ParseHashV``ParseHashO` `ParseHexV` `ParseHexO` `HelpExampleCli` and `HelpExampleRpc` move from `rpc/server.cpp` to `rpc/util.cpp`
- `AmountHighWarn` and `AmountErrMsg` move from `ui_interface.cpp` to `util/error.cpp`
- `FormatStateMessage` and `strMessageMagic` move from `validation.cpp` to `util/validation.cpp`
- `VerifyWallets` `LoadWallets` `StartWallets` `FlushWallets` `StopWallets` and `UnloadWallets` move from `wallet/init.cpp` to `wallet/node.cpp`

Adds the following util units and adds them to libbitcoin_util:
- `util/url.cpp` takes `urlDecode` from `httpserver.cpp`
- `util/error.cpp` takes `TransactionErrorString` from
`node/transaction.cpp` and `AmountHighWarn` and `AmountErrMsg` from
`ui_interface.cpp`
- `util/fees.cpp` takes `StringForFeeReason` and `FeeModeFromString` from `policy/fees.cpp`
- `util/rbf.cpp` takes `SignalsOptInRBF` from `policy/rbf.cpp`
- 'util/validation.cpp` takes `FormatStateMessage` and `strMessageMagic` from 'validation.cpp`
This moves the following policy settings functions and globals to a new
src/policy/settings unit in lib_server:
- `incrementalRelayFee`
- `dustRelayFee`
- `nBytesPerSigOp`
- `fIsBareMultisigStd`
These settings are only required by the node and should not be accessed
by other libraries.

Pull request description:
This PR makes a number of improvements to the InvalidateBlock (`invalidateblock` RPC) and RewindBlockIndex functions, primarily around breaking up their long-term cs_main holding. In addition:
* They're made safely interruptible (`bitcoind` can be shutdown, and no progress in either will be lost, though if incomplete, `invalidateblock` won't continue after restart and will need to be called again)
* The validation queue is prevented from overflowing (meaning `invalidateblock` on a very old block will not drive bitcoind OOM) (see #14289).
* `invalidateblock` won't bother to move transactions back into the mempool after 10 blocks (optimization).
This is not an optimal solution, as we're relying on the scheduler call sites to make sure the scheduler doesn't overflow. Ideally, the scheduler would guarantee this directly, but that needs a few further changes (moving the signal emissions out of cs_main) to prevent deadlocks.
I have manually tested the `invalidateblock` changes (including interrupting, and running with -checkblockindex and -checkmempool), but haven't tried the rewinding (which is probably becoming increasingly unnecessary, as very few pre-0.13.1 nodes remain that would care to upgrade).

Pull request description:
This cleans up and refactors block file helpers so that they may be used by the block filter indexer. Per [design discussion](https://github.com/bitcoin/bitcoin/pull/14121#issuecomment-451252591) about storing BIP 157 block filters, it has been suggested that they are stored in the same way as block and undo data. This refactor is sufficient to simplify file operations for this use case, though in the future perhaps more pruning-related logic ought to be moved into the new classes.
The basic abstraction is a `FlatFileSeq` which manages access to a sequence of numbered files into which raw data is written.

But ```m_config_sections.clear()``` in ```ArgsManager::ReadConfigStream()``` is called every time when reading each configuration file, so it can warn about only last reading file if ```includeconf``` exists.
This PR fix lack of warning by collecting all section names by moving ```m_config_sections.clear()``` to ```ArgsManager::ReadConfigFiles()``` .
Also add a test code to confirm this situation.

3f5ad622e5 Enable PID file creation on Windows - Add available WIN PID function - Consider WIN32 in each relevant case - Add new preprocessor definitions to suppress warning - Update error message for generic OS (riordant)
Pull request description:
# Introduction
As discussed with @laanwj on IRC:
- PID file creation was never enabled for Windows, as the `pid_t` filetype is not available for it. However, the WIN32 API contains the header [`Processthreadsapi.h`](https://github.com/CodeShark/x86_64-w64-mingw32/blob/master/include/processthreadsapi.h) which in turn contains the function [`GetCurrentProcessId()`](https://docs.microsoft.com/en-gb/windows/desktop/api/processthreadsapi/nf-processthreadsapi-getcurrentprocessid). ~~This function is called at a higher level by [`_getpid()`](https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/getpid?view=vs-2017)~~ EDIT: `_getpid()` is not available to the MSVC compiler used in the AppVeyor build. As a result, I have changed the function call to`GetCurrentProcessId()`, which performs the same function and is available to both MinGW & MSVC.
This allows one to capture the PID in Windows, without any additional includes - the above function is already available.
- Within this PR, I have added a separate line that calls `GetCurrentProcessId()` in the case of a WIN compilation, and the usual `getpid()` otherwise. All code blocks processing PID file logic that avoid WIN32 have been changed to consider it. I have also updated the preprocessor definitions in `libbitcoin_server.vcxproj.in` to suppress a warning related to `std::strerror` for the MSVC build, that was causing the AppVeyor build to fail (see @fanquake comment below).
# Rationale
- Consistency between OS's running Bitcoin
- Applications which build off of `bitcoind`, such as novel front-end clients, often need access to the PID in order to control the daemon. Instead of designing some alternate way of doing this for one system, it should be consistent between all of them.

1. `CreatePidFile()` has been moved from `util/system.cpp` to `init.cpp` for the following reasons:
- to get the ability to use `InitError()`
- now `init.cpp` contains code of both creating PID file and removing it
2. Regarding 0.18 release process: this PR modifies 1 string and introduces 2 new ones.

6f6514a080 Correct units for "-dbcache" and "-prune" (Hennadii Stepanov)
Pull request description:
Actually, all `dbcache`-related values in the code are measured in MiB (not in megabytes, MB) or in bytes (e.g., `nTotalCache`).
See: https://github.com/bitcoin/bitcoin/blob/master/src/txdb.hba8c8b2227/src/init.cpp (L1405-L1424)
Also, "-prune" is fixed:
1. The GUI values in GB are translated to the node values in MiB correctly.
2. The maximum of the "prune" `QSpinBox` is not limited by default value of 99 (GB).
Fix: #15106

All dbcache-related values in the code are measured in MiB (not in
megabytes, MB) or in bytes.
The GUI "-prune" values in GB are translated to the node values in MiB
correctly. The maximum of the "-prune" QSpinBox is not limited by the
default value of 99 (GB).
Also, this improves log readability.
This commit attempts to clarify and correct the `-blocksdir` argument
description and default value. `-blocksdir` does not refer to the full
path to the actual `blocks` directory, but rather the root/parent
directory which contains the `blocks` directory. Accordingly, the
default value is `<datadir>` and not `<datadir>/blocks`. It also
attempts to clarify that only the `.dat` files containing block data are
impacted by `-blocksdir`, not the index files.

c3f1821ac7 Make blockdir always net specific (Hennadii Stepanov)
Pull request description:
The blocks directory is net specific by definition.
Also this prevents the side effect of calling `GetBlocksDir(false)` in the non-mainnet environment.
Currently a new node creates an unused `blocks\` directory in the root of the data directory when `-testnet` or `-regtest` is specified.

645e905c32 doc: Add release notes for unloadwallet change to synchronous call (João Barbosa)
c37851de57 rpc: Make unloadwallet wait for complete wallet unload (João Barbosa)
Pull request description:
Currently the `unloadwallet` RPC is asynchronous, it only signals the intent to unload the wallet and then returns the response to the client. The actual unload can happen later and the client has no way to be notified of that.
This PR makes the `unloadwallet` RPC synchronous, meaning that it blocks until the wallet is fully unloaded.
Replaces #14919, fixes#14917.

48b37db50 make peertimeout a debug argument, remove error message translation (Zain Iqbal Allarakhia)
8042bbfbf p2p: allow p2ptimeout to be configurable, speed up slow test (Zain Iqbal Allarakhia)
Pull request description:
**Summary:**
1. _Primary_: Adds a `debug_only=true` flag for peertimeout, defaults to 60 sec., the current hard-coded setting.
2. _Secondary_: Drastically speeds up `p2p_timeout.py` test.
3. _Secondary_: Tests that the correct code path is being tested by adding log assertions to the test.
**Rationale:**
- P2P timeout was hard-coded: make it explicitly specified and configurable, instead of a magic number.
- Addresses #13518; `p2p_timeout.py` takes 4 sec. to run instead of 61 sec.
- Makes `p2p_timeout.py` more explicit. Previously, we relied on a comment to inform us of the timeout amount being tested. Now it is specified directly in the test via passing in the new arg; `-peertimeout=3`.
- Opens us up to testing more P2P scenarios; oftentimes slow tests are the reason we don't test.

In the config file, sections are specified by square bracket pair "[]"$,
or included in the option name itself which separated by a period"(.)".
Typicaly, [testnet] is not a correct section name and specified options
in that section are ignored but user cannot recognize what is happen.
So, add some log/stderr-warning messages if unrecognized section names
are present in the config file after checking section only args.
Route calls during node initialization and shutdown that would happen between a
node process and wallet processes through the serializable `Chain::Client`
interface, rather than `WalletInitInterface` which is now simpler and only
deals with early initialization and parameter interaction.
This commit mostly does not change behavior. The only change is that the
"Wallet disabled!" and "No wallet support compiled in!" messages are now logged
earlier during startup.
This commit does not change behavior. All it does is pass new function
parameters.

3ccfa34b32 convert C-style (void) parameter lists to C++ style () (Arvid Norberg)
Pull request description:
In C, an empty parameter list, `()`, means the function takes any arguments, and `(void)` means the function does not take any parameters.
In C++, an empty parameter list means the function does not take any parameters.
So, C++ still supports `(void)` parameter lists with the same semantics, why change to `()`?
1. removing the redundant `void` improves signal-to-noise ratio of the code
2. using `(void)` exposes a rare inconsistency in that a template taking a template `(T)` parameter list, cannot be instantiated with `T=void`

I don't understand why `-help-debug` would be useful without requesting
the help, and I've made this particular mistake one time too many.
(ok, so apparently the original reason that -help-debug is an option is
to show debug options in the GUI option overview? that seems very
unlikely to ever be used, if someone wants to add a way to show debug
options in the GUI it'd be better to have a check box)

PR #12713 changed the interpretation for negation of non-boolean options
(e.g. -noconnect) to no longer set the option to 0, but to remove it
from the options.
I think this is better because it gets rid of the special meaning of
'0'.
However it needs to be documented. I attempt to do so in this PR.

fa5ce27385 ui: Compile boost:signals2 only once (MarcoFalke)
Pull request description:
ui is one of the modules that poison other modules with `boost/signals2` headers. This moves the include to the cpp file and uses a forward declaration in the header.
Locally this speeds up the incremental build (building everything that uses the ui module) with gcc by ~5% for me. Gcc uses ~5% less memory.
Would be nice if someone could verify the numbers roughly.
I presume the improvements will be more pronounced if the other models would stop exposing the boost header as well.

As part of a larger effort to decouple net_processing and validation a bit, these are a bunch of simple scope cleanups. I've moved things out of the header file that are only referenced in net_processing and added static (or anonymous namespace) modifiers to everything possible in net_processing.
There are a handful of functions which could be static except that they are exposed for the sake of unit testing - these are explicitly commented. There has been some discussion of a compile time annotation, but no conclusion has been reached on that yet.
This is somewhat related to other prs #12934#13413#13407 and will be followed by prs that reduce reliance on cs_main to synchronize data structures which are translation unit local to net_processing

#13004 changed the default behavior for printtoconsole but this has not been reflected in the command line help.
This fixes the description of -printtoconsole to reflect this change, and also provides the user with missing information on how to explicitly disable logging to debug.log.
At present I have made the latter update to two separate places (-printtoconsole and -debuglogfile) because a user looking for information on how to disable logging is probably going to look in the "Debugging/Testing Options" section. Moving -debuglogfile from the "General" options category to the "Debugging/Testing" section could potentially remove the need for this redundancy but may be out of the scope of this PR.
2dcd7b4ec logging: avoid nStart may be used uninitialized in AppInitMain warning (mruddy)

LogPrintf(" block index %15dms\n", GetTimeMillis() - nStart);
```
It's ok without this PR, but this PR renames `nStart` to `load_block_index_start_time`, makes it `const`, and also reduces the scope of the variable.
The logging line is moved such that the the time spent will be logged even if a shutdown is requested while the index is being loaded.
Having the log message output even when a shutdown is requested may be how this was intended to work before anyways. That could explain the leading space, as such a log message now looks like:
```
2018-06-30T11:34:05Z [0%]...[16%]...[33%]...[50%]... block index 25750ms

This adds a new RPC method "getzmqnotifications", which returns

9b72c988a0 scripted-diff: Avoid temporary copies when looping over std::map (Ben Woosley)
Pull request description:
The ::value_type of the std::map/std::multimap/std::unordered_map containers is

Make these options "available" by adding them to the hidden options

Ignore unknown options in the config file for bitcoin-cli
Fix tests and bitcoin-cli to match actual options used
Many options are extremely technical, and refer internals, making it
difficult to translate usefully. This came up in discussion of e.g.
#10949. If a message is not understood by translators (which are
typically end-users, not developers) they'll either translate it
literally, making it harder to understand instead of easier, with the
added drawback of the user no longer being able to google it.
Also the translation was only working for bitcoin-qt as with
the console programs, there is no translation backend. So it was
injecting never-used translation messages for bitcoin-cli, -tx.
For these reasons, stop translating options help completely. This should
not affect the output **in any way** except for bitcoin-qt when a
non-English language is configured in the locale.
This implements #10962.
This commit adds a boolean option `-enablebip61`, defaulting to `1`, that
can be used to disable the sending of BIP61 `reject` messages. This
functionality has been requested for various reasons:
- security (DoS): reject messages can reveal internal state that can be
used to target certain resources such as the mempool more easily.
- bandwidth: a typical node sends lots of reject messages; this counts
against upstream bandwidth. Also the reject messages tend to be larger
than the message that was rejected.
On the other hand, reject messages can be useful while developing client
software (I found them indispensable while creating bitcoin-submittx),
as well as for our own test cases, so whatever the default becomes on the
long run, IMO the functionality should be retained as option. But that's
a discussion for later.

The weekly meeting on [2017-12-07](http://www.erisian.com.au/meetbot/bitcoin-core-dev/2017/bitcoin-core-dev.2017-12-07-19.00.log.html) discussed allowing options to bitcoin to have some sensitivity to what network is in use. @theuni suggested having sections in the config file:
<cfields> an alternative to that would be sections in a config file. and on the
cmdline they'd look like namespaces. so, [testnet] port=5. or -testnet::port=5.
This approach is (more or less) supported by `boost::program_options::detail::config_file_iterator` -- when it sees a `[testnet]` section with `port=5`, it will treat that the same as "testnet.port=5". So `[testnet] port=5` (or `testnet.port=5` without the section header) in bitcoin.conf and `-testnet.port=5` on the command line.
The other aspect to this question is possibly limiting some options so that there is no possibility of accidental cross-contamination across networks. For example, if you're using a particular wallet.dat on mainnet, you may not want to accidentally use the same wallet on testnet and risk reusing keys.
I've set this up so that the `-addnode` and `-wallet` options are `NETWORK_ONLY`, so that if you have a bitcoin.conf:
wallet=/secret/wallet.dat
upnp=1
and you run `bitcoind -testnet` or `bitcoind -regtest`, then the `wallet=` setting will be ignored, and should behave as if your bitcoin.conf had specified:
upnp=1
[main]
wallet=/secret/wallet.dat
For any `NETWORK_ONLY` options, if you're using `-testnet` or `-regtest`, you'll have to add the prefix to any command line options. This was necessary for `multiwallet.py` for instance.
I've left the "default" options as taking precedence over network specific ones, which might be backwards. So if you have:
maxmempool=200
[regtest]
maxmempool=100
your maxmempool will still be 200 on regtest. The advantage of doing it this way is that if you have `[regtest] maxmempool=100` in bitcoin.conf, and then say `bitcoind -regtest -maxmempool=200`, the same result is probably in line with what you expect...
The other thing to note is that I'm using the chain names from `chainparamsbase.cpp` / `ChainNameFromCommandLine`, so the sections are `[main]`, `[test]` and `[regtest]`; not `[mainnet]` or `[testnet]` as might be expected.

When network-specific options such as -addnode, -connect, etc are
specified in the default section of the config file, but that setting is
ignored due to testnet or regtest being in use, and it is not overridden
by either a command line option or a setting in the [regtest] or [test]
section of the config file, a warning is added to the log, eg:
Warning: Config setting for -connect only applied on regtest network when in [regtest] section.

d54874d Set SCHED_BATCH priority on the loadblk thread. (Evan Klitzke)
Pull request description:
Today I came across #10271, and while reading the discussion #6358 was linked to. Linux systems have a `SCHED_BATCH` scheduler priority that is useful for threads like loadblk. You can find the full details at [sched(7)](http://man7.org/linux/man-pages/man7/sched.7.html), but I'll quote the relevant part of the man page below:
> ...this policy will cause the scheduler to always assume that the thread is
CPU-intensive. Consequently, the scheduler will apply a small scheduling penalty
with respect to wakeup behavior, so that this thread is mildly disfavored in
scheduling decisions.
>
> This policy is useful for workloads that are noninteractive, but do not want to
lower their nice value, and for workloads that want a deterministic scheduling
policy without interactivity causing extra preemptions (between the workload's
tasks).
I think this change is useful independently of #10271 and irrespective of whether that change is merged. Under normal operation the loadblk thread will just import `mempool.dat`. However, if Bitcoin is started with `-reindex` or `-reindex-chainstate` this thread will use a great deal of CPU while it rebuilds the chainstate database (and the block database in the case of `-reindex`). By setting `SCHED_BATCH` this thread is less likely to interfere with interactive tasks (e.g. the user's web browser, text editor, etc.).
I'm leaving the nice value unchanged (which also affects scheduling decisions) because I think that's better set by the user. Likewise I'm not using [ioprio_set(2)](http://man7.org/linux/man-pages/man2/ioprio_set.2.html) because it can cause the thread to become completely I/O starved (and knowledgeable users can use `ionice(1)` anyway).

Most logs should terminated with a '\n'. Some logs
are built up over multiple calls to logPrintf(), so
do not need a newline terminater. Comment all of
these 'continued' logs as a linter hing.
Log messages should terminate with a '\n', or the following log will be
written to the same line without a timestamp. Fix a couple of cases
where the message is not terminated with a \n.

Pull request description:
Since the actual block files taking up more and more space, it may be desirable to have them stored in a different location then the data directory (use case: SSD for chainstate, etc., HD for blocks).
This PR adds a `-blocksdir` option that allows one to keep the blockfiles and the blockindex external from the data directory (instead of creating symlinks).
I fist had an option to keep the blockindex within the datadir, but seems to make no sense since accessing the index will (always) lead to access (r/w) the block files.

Rationale (from Bjarne Stroustrup's ["C++11 FAQ"](http://www.stroustrup.com/C++11FAQ.html#enum)):
>
> The enum classes ("new enums", "strong enums") address three problems with traditional C++ enumerations:
>
> * conventional enums implicitly convert to int, causing errors when someone does not want an enumeration to act as an integer.
> * conventional enums export their enumerators to the surrounding scope, causing name clashes.
> * the underlying type of an enum cannot be specified, causing confusion, compatibility problems, and makes forward declaration impossible.
>
> The new enums are "enum class" because they combine aspects of traditional enumerations (names values) with aspects of classes (scoped members and absence of conversions).

While reading another PR I saw a mention of #6358. The use case for
SCHED_BATCH is to hint to the kernel that the thread is running a
non-interactive workload that consumes a lot of CPU time. This is
helpful on desktop machines where the loadblk thread can interfere with
interactive applications. More details can be found in the sched(7) man
page.
