fafd121026 refactor: Make CFeeRate constructor architecture-independent (MarcoFalke)
Pull request description:
Currently the constructor is architecture dependent. This is confusing for several reasons:
* It is impossible to create a transaction larger than the max value of `uint32_t`, so a 64-bit `size_t` is not needed
* Policy (and consensus) code should be arch-independent
* The current code will print spurious compile errors when compiled on 32-bit systems:
```
policy/feerate.cpp:23:22: warning: result of comparison of constant 9223372036854775807 with expression of type 'size_t' (aka 'unsigned int') is always true [-Wtautological-constant-out-of-range-compare]
assert(nBytes_ <= uint64_t(std::numeric_limits<int64_t>::max()));
```
Fix all issues by making it arch-independent. Also, fix `{}` style according to dev notes.

Pull request description:
This PR is a follow up PR to #21244. The PR attempts to move us an inch towards the [goal](https://github.com/bitcoin/bitcoin/pull/21244#discussion_r615307465) by removing `GetDataDir(net_specific)` and replacing it by `gArgs.GetDataDir(net_specific)` calls.
The approach of this PR attempts to be similar to the one chosen in "De-globalize ChainstateManager" (#20158). The goal is to pass `ArgsManager` to functions (or ideally to have `ArgsManager` as a member of a class where needed; inspiration from here: #21789) instead of having it as a global variable (i.e. `gArgs`).
**Notes:**
* First commit makes `m_cached_blocks_path` `mutable` as was suggested [here](https://github.com/bitcoin/bitcoin/pull/21244#discussion_r615274095) but not fully applied in #21244. (`m_cached_datadir_path` and `m_cached_network_datadir_path` were marked as `mutable` in #21244) This commit can be in a separate PR too.
* Other commits deal with removing of `GetDataDir(net_specific)` function.
* This was originally part of #21244 but it was [left]((https://github.com/bitcoin/bitcoin/pull/21244#pullrequestreview-633779754)) for a follow up PR.
* I think that the proposed changes show nicely where there is reliance on `gArgs` which is IMO a good thing.
If you know about a better approach how to do this, please share it here.

fad0867d6a Cleanup -includeconf error message (MarcoFalke)
fa9f711c37 Fix crash when parsing command line with -noincludeconf=0 (MarcoFalke)
Pull request description:
The error message has several issues:
* It may crash instead of cleanly shutting down, when `-noincludeconf=0` is passed
* It doesn't quote the value
* It includes an erroneous trailing `\n`
* It is redundantly mentioning `"-includeconf cannot be used from commandline;"` several times, when once should be more than sufficient
Fix all issues by:
* Replacing `get_str()` with `write()` to fix the crash and quoting issue
* Remove the `\n` and only print the first value to fix the other issues
Before:
```

Define the Package type as an alias for a vector of transactions for now.
Add PackageValidationResult, similar to TxValidationResult and
BlockValidationResult for package-wide errors that cannot be reported
within a single transaction result, such as having too many
transactions in the package. We can update the concept of
what a package is and have different logic for packages vs lists of
transactions in the future, e.g. for package relay.
Allow CheckSequenceLocks to use heights and coins from any CoinsView and
CBlockIndex provided. This means that CheckSequenceLocks() doesn't need
to hold the mempool lock or cs_main. The caller is responsible for
ensuring the CoinsView and CBlockIndex are consistent before passing
them in. The typical usage is still to create a CCoinsViewMemPool from
the mempool and grab the CBlockIndex from the chainstate tip.

4ee9ee7236 qt: Use native presentation of shortcut (Hennadii Stepanov)
Pull request description:
On `master` the only way to resize the console font is to manually move your mouse and click the resize buttons. This PR introduces convenient keyboard shortcuts to resize the console font.
The common resize shortcuts for applications are `Ctrl+=`/`Ctrl++` and `Ctrl+-`/`Ctrl+_`. This means that the resize QPushButtons need two shortcuts each, but you cannot assign multiple shortcuts to a QPushButton. See: https://doc.qt.io/qt-5/qabstractbutton.html#shortcut-prop
To get around this, we introduce a new function in `guiutil`, which connects a supplied `QKeySequence` shortcut to a `QAbstractButton`. This function can be reused in other situations where more than one shortcut is needed for a button.

Instead of hijacking the effective_feerate to use the correct value
during coin selection, have OutputGroup be aware of whether we are
subtracting the fee from the outputs and provide the correct value to
use for selection.
To do this, OutputGroup now takes CoinSelectionParams and has a new
function GetSelectionAmount().
This was originally modified to use SelectCoinsMinConf in order to test
both BnB and Knapsack at the same time. But since SelectCoins does both
now, this is no longer necessary and we can revert back to actually
testing SelectCoins.
Remove the CreateTransaction while loop. Removes variables that were
only needed because of that loop. Also renames a few variables and
moves their declarations to where they are used.
Some subtractFeeFromOutputs handling is moved to after coin selection
in order to reduce their amounts once the fee is known.
If subtracting the fee reduces the change to dust, we will also now
remove the change output
Although the CreateTransaction loop currently remains, it should be
largely unused. KnapsackSolver will now account for transaction fees
when doing its selection.
In the previous commit, SelectCoinsMinConf was refactored to have some
calculations become shared for KnapsackSolver and SelectCoinsBnB. In
this commit, KnapsackSolver will now use the not_input_fees and
effective_feerate so that it include the fee for non-input things
(excluding a change output) so that the algorithm will select enough to
cover those fees. This is necessary for selecting on effective values.
Additionally, the OutputGroups
created for KnapsackSolver will actually have their effective values
calculated and set, and KnapsackSolver will do its selection on those
effective values.
Lastly, SelectCoins is modified to use the same value for preselected
inputs for BnB and KnapsackSolver. While it will still use the real
value when subtracting the fee from outputs, this behavior will be
the same regardless of the algo used for selecting additional inputs.
The fees for transaction overhead and recipient outputs are now included
in nTargetValue instead of being a separate parameter. For the coin
selection algorithms, it doesn't matter that these are separate as in
either case, the algorithm needs to select enough to cover these fees.
Note that setting nValueToSelect is changed as it now includes
not_input_fees. Without the change to how nValueToSelect is increased
for KnapsackSolver, this would result in overpaying fees. The change to
increase by the difference between nFeeRet and not_input_fees allows
this to have the same behavior as previously.
Additionally, because we assume that KnapsackSolver will always find a
solution that requires change (we assume that BnB always finds a
non-change solution), we also include the fee for the change output in
KnapsackSolver's target. As part of this, we also use the changeless
nFeeRet when iterating for KnapsackSolver. This is because we include
the change fee when doing KnapsackSolver, so nFeeRet on further
iterations won't include the change fee.
Simplifies CreateTransactionInternal without changing behavior. Removes
the pick_new_inputs variable by moving the subtract fee from amount
implementation to later in the loop to where it is possible to calculate
the fee for the transaction. This allows the fee to be subtracted from
the outputs within a single iteration, instead of calculating the fee in
the first iteration, and subtracting the fee in the second.
This also removes another scenario where a second iteration of the loop
finds a smaller input set (and thus smaller fees than the first
iteration) with no change and so a third iteration of the loop is done in order to make
a change output that contains the excess fees.
To handle these cases, we always create a change output which contains
the difference between selected input values and the recipient amounts.
Once the transaction fee is calculated, the change output is reduced (in
the normal case) or the recipient amounts are reduced (in the subtract
fee from amount case). All of this is done in a single iteration of the
loop.
Feefilter option is debug only and it isn't used in any tests, it's wasteful
to check this option for every peer on every iteration of the message handler
loop. refs #21545

This is a followup for https://github.com/bitcoin/bitcoin/pull/20365#discussion_r522265003
First part of a refactoring with overall goal to simplify `CWallet` and de-duplicate code with `wallettool`
**Rationale**: split `CWallet::Create` and create `CWallet::AttachChain`.
`CWallet::AttachChain` takes chain as first parameter on purpose. In future I suggest we can remove `chain` from `CWallet` constructor.

74bf850ac4 faster HexStr => 13% faster blockToJSON (Martin Ankerl)
Pull request description:
`std::string`'s push_back is rather slow because it needs to check & update the string size. For
`HexStr` the output string size is already easily know, so we can initially create the string with
the correct size and then just assign the data.
`HexStr` is heavily usd in `blockToJSON`, so this change is a noticeable benefit. Benchmark on an i7-8700 @3.2GHz:
* 71,315,461.00 ns/op master
* 62,842,490.00 ns/op this commit
So this little change makes `blockToJSON` about ~13% faster.

105941b726 net: use stronger AddLocal() for our I2P address (Vasil Dimov)
Pull request description:
There are two issues:
### 1. Our I2P address not added to local addresses.
* `externalip=` is used with an IPv4 address (this sets automatically `discover=0`)
* No `discover=1` is used
* `i2psam=` is used
* No `externalip=` is used for our I2P address
* `listenonion=1 torcontrol=` are used
In this case `AddLocal(LOCAL_MANUAL)` [is used](94f83534e4/src/torcontrol.cpp (L354)) for our `.onion` address and `AddLocal(LOCAL_BIND)` [for our](94f83534e4/src/net.cpp (L2247)) `.b32.i2p` address, the latter being [ignored](94f83534e4/src/net.cpp (L232-L233)) due to `discover=0`.
### 2. Our I2P address removed from local addresses even if specified with `externalip=` on I2P proxy restart.
* `externalip=` is used with our I2P address (this sets automatically `discover=0`)
* No `discover=1` is used
* `i2psam=` is used
In this case, initially `externalip=` causes our I2P address to be [added](94f83534e4/src/init.cpp (L1266)) with `AddLocal(LOCAL_MANUAL)` which overrides `discover=0` and works as expected. However, if later the I2P proxy is shut down [we do](94f83534e4/src/net.cpp (L2234)) `RemoveLocal()` in order to stop advertising our I2P address (since we have lost I2P connectivity). When the I2P proxy is started and we reconnect to it, restoring the I2P connectivity, [we do](94f83534e4/src/net.cpp (L2247)) `AddLocal(LOCAL_BIND)` which does nothing due to `discover=0`.
To resolve those two issues, use `AddLocal(LOCAL_MANUAL)` for I2P which is also what we do with Tor.

29c9e2c2d2 wallet: Do not iterate a directory if having an error while accessing it (Hennadii Stepanov)
Pull request description:
On Windows when `ListDatabases` tries to iterate any system folder, e.g., "System Volume Information", it falls into an infinite loop.
This PR fixes this bug. Now the `debug.log` contains:
```
2021-05-12T09:07:53Z ListDatabases: Access is denied D:/System Volume Information -- skipping.
```
An easy way to reproduce the bug and test this PR is to pass the `-walletdir=D:\` command-line option, and run the `listwalletdir` RPC, or File -> Open Wallet in the GUI menu.
Fixes#20081.
Fixes#21136.
Fixes#21904.

c30dd02cd8 refactor: remove redundant fOnlySafe argument (t-bast)
Pull request description:
The `fOnlySafe` argument to `AvailableCoins` is now redundant, since #21359 added a similar field inside the `CCoinControl` struct (see https://github.com/bitcoin/bitcoin/pull/21359#discussion_r591578684).
Not all code paths create a `CCoinControl` instance, but when it's missing we can default to using only safe inputs which is backwards-compatible.

nMessageSize is uint32_t and is set to -1. This will warn with `-fsanitize=implicit-integer-sign-change` when V1TransportDeserializer calls into the ctor. This pull initializes nMessageSize to `numeric_limits<uint32_t>::max()` instead and removes the ubsan suppression.

faad68fcd4 index: Avoid async shutdown on init error (MarcoFalke)
Pull request description:
An async shutdown during init is confusing when a simple boolean return value can be used for a synchronous shutdown.
This also changes the error message on stderr from:
```
Error: A fatal internal error occurred, see debug.log for details
Error: A fatal internal error occurred, see debug.log for details
```
To:
```
Error: basic block filter index best block of the index goes beyond pruned data. Please disable the index or reindex (which will download the whole blockchain again)
