Pull request description:
Implements #8263.
Qt4.x has been EOL since 2015, and at least Gentoo has, or is going to drop support for it. I wouldn't be surprised if other Linux distributions follow.
This removes Qt4 detection from the build system, as well as removes all Qt4 fallbacks from the code. Turns out there's more than I expected: this is going to make maintenance of the GUI code, as well as adding new features significantly easier.
(I know there's still some references left to qt4 in RPM and Debian build script, but I don't have the knowledge how to fix them)

If an unknown option is given via either the command line args or
the conf file, throw an error and exit
Update tests for ArgsManager knowing args
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.
Default `-printtoconsole` to false for the GUI. GUI programs should not
print to the console unnecessarily. For example, when launched by the
window manager, the output might end up in the X session log file,
resulting in duplicate logging. On Windows, it is pointless as well
because bitcoin-qt isn't a console application.

Pull request description:
This is a refactoring PR that does not change behavior in any way. This change:
1. Creates abstract [`Node`](https://github.com/ryanofsky/bitcoin/blob/pr/ipc-local/src/interface/node.h) and [`Wallet`](https://github.com/ryanofsky/bitcoin/blob/pr/ipc-local/src/interface/wallet.h) interfaces in [`src/interface/`](https://github.com/ryanofsky/bitcoin/tree/pr/ipc-local/src/interface)
1. Updates Qt code to call the new interfaces. This largely consists of diffs of the form:
```diff
- InitLogging();
- InitParameterInteraction();
+ node.initLogging();
+ node.initParameterInteraction();
```
This change allows followup PR #10102 (makes `bitcoin-qt` control `bitcoind` over an IPC socket) to work without any significant updates to Qt code. Additionally:
* It provides a single place to describe the interface between GUI and daemon code.
* It can make better GUI testing possible, because Node and Wallet objects have virtual methods that can be overloaded for mocking.
* It can be used to help make the GUI more responsive (see https://github.com/bitcoin/bitcoin/issues/10504)
Other notes:
* I used python scripts [hide-globals.py](https://github.com/ryanofsky/home/blob/master/src/2017/hide-globals/hide-globals.py) and [replace-syms.py](https://github.com/ryanofsky/home/blob/master/src/2017/hide-globals/replace-syms.py) to identify all the places where Qt code was accessing libbitcoin global variables and calling functions accessing those global variables.
* These changes were originally part of #10102. Thanks to @JeremyRubin for the suggestion of splitting them out.

Pull request description:
This continues the work of #7965. This PR, along with several others, would remove the remaining dependencies from libbitcoin_server.a on libbitcoin_wallet.a.
To create the interface, I've just translated all the old init.cpp wallet function calls into an interface class. I've not done any thinking about whether it makes sense to change that interface by combining/splitting those calls. This is a purely internal interface, so there's no problem in changing it later.

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.

This commit creates a global g_wallet_init_interface, which is created
in bitcoind and bitcoin-qt. g_wallet_init_interface is used to init
and destroy the wallet.
This removes the dependency from init.cpp on the wallet library.

9ad6746ccd Use static_cast instead of C-style casts for non-fundamental types (practicalswift)
Pull request description:
A C-style cast is equivalent to try casting in the following order:
1. `const_cast(...)`
2. `static_cast(...)`
3. `const_cast(static_cast(...))`
4. `reinterpret_cast(...)`
5. `const_cast(reinterpret_cast(...))`
By using `static_cast<T>(...)` explicitly we avoid the possibility of an unintentional and dangerous `reinterpret_cast`. Furthermore `static_cast<T>(...)` allows for easier grepping of casts.

This resolves#12229 which pointed out a shutdown deadlock due to
scheduler/checkqueue having been shut down while network message
processing is still running.
This makes all include paths in the GUI absolute.
Many changes are involved as every single source file in
src/qt/ assumes to be able to use relative includes.

Alternative to #10818, alternative solution to #10815.
After this change: All the AppInit steps before and inclusive
AppInitLockDataDirectory must not have Shutdown() called in case of
failure. Only when AppInitMain fails, Shutdown should be called.
Changes the GUI and bitcoind code to consistently do this.
This changes the logging categories to boolean flags instead of strings.
This simplifies the acceptance testing by avoiding accessing a scoped
static thread local pointer to a thread local set of strings. It
eliminates the only use of boost::thread_specific_ptr outside of
lockorder debugging.
This change allows log entries to be directed to multiple categories
and makes it easy to change the logging flags at runtime (e.g. via
an RPC, though that isn't done by this commit.)
It also eliminates the fDebug global.
Configuration of unknown logging categories now produces a warning.
- Change initializeResult(int) to initializeResult(bool) to avoid
implicit type conversion.
- Use EXIT_FAILURE and EXIT_SUCCESS instead of magic numbers.
- Remove the argument from shutdownResult(int); it was called with a
constant argument.

16ca0bf init: Try to aquire datadir lock before and after daemonization (Wladimir J. van der Laan)
0cc8b6b init: Split up AppInit2 into multiple phases (Wladimir J. van der Laan)
Make splash screen queue its own deletion when it receives the finished
command, instead of relying on WA_DeleteOnClose which doesn't work under
these circumstances.
Make ownership of the QThread object clear, so that the RPCConsole
can wait for the executor thread to quit before shutdown is called. This
increases overall thread safety, and prevents some objects from leaking
on exit.
- `--help`, `--version` etc should exit with `0` i.e. no error ("not enough args" case should still trigger an error)
- error reading config file should exit with `1`
Slightly refactor AppInitRPC/AppInitRawTx to return standard exit codes (EXIT_FAILURE/EXIT_SUCCESS) or CONTINUE_EXECUTION (-1)
The `pickDataDirectory()` function was calling `exit(0)` to quit
the application when the user closes the dialog without choosing
a data directory.
This is a bad idea because a background thread is created (to
check free space on the drive of the currently selected datadir).
The thread is not stopped and unwound properly, resulting in a potential
race condition somewhere deep in Qt.
So replace the `exit()` by a boolean return value, and let the
stack unwind normally.
- *Replace usage of boost::asio with [libevent2](http://libevent.org/)*.
boost::asio is not part of C++11, so unlike other boost there is no
forwards-compatibility reason to stick with it. Together with #4738 (convert
json_spirit to UniValue), this rids Bitcoin Core of the worst offenders with
regard to compile-time slowness.
- *Replace spit-and-duct-tape http server with evhttp*. Front-end http handling
is handled by libevent, a work queue (with configurable depth and parallelism)
is used to handle application requests.
- *Wrap HTTP request in C++ class*; this makes the application code mostly
HTTP-server-neutral
- *Refactor RPC to move all http-specific code to a separate file*.
Theoreticaly this can allow building without HTTP server but with another RPC
backend, e.g. Qt's debug console (currently not implemented) or future RPC
mechanisms people may want to use.
- *HTTP dispatch mechanism*; services (e.g., RPC, REST) register which URL
paths they want to handle.
By using a proven, high-performance asynchronous networking library (also used
by Tor) and HTTP server, problems such as #5674, #5655, #344 should be avoided.
What works? bitcoind, bitcoin-cli, bitcoin-qt. Unit tests and RPC/REST tests
pass. The aim for now is everything but SSL support.
Configuration options:
- `-rpcthreads`: repurposed as "number of work handler threads". Still
defaults to 4.
- `-rpcworkqueue`: maximum depth of work queue. When this is reached, new
requests will return a 500 Internal Error.
- `-rpctimeout`: inactivity time, in seconds, after which to disconnect a
client.
- `-debug=http`: low-level http activity logging
Introduce a PlatformStyle to handle platform-specific customization of
the UI.
This replaces 'scicon', as well as #ifdefs to determine whether to place
icons on buttons.
The selected PlatformStyle defaults to the platform that the application
was compiled on, but can be overridden from the command line with
`-uiplatform=<x>`.
Also fixes the warning from #6328.
QT_NO_KEYWORDS prevents Qt from defining the `foreach`, `signals`,
`slots` and `emit` macros.
Avoid overlap between Qt macros and boost - for example #undef hackiness
in #6421.
Mainly cleanups: Gets rid of isTestNet everywhere, by keeping track
of network-specific theming in a central place.
Also makes GUI no longer dependent on the network ID enumeration, which
alleviates concerns about #4802.
It's strange to be able to close these windows while there is work
in progress.
Also set Qt::WA_DeleteOnClose on both windows to make sure that they
are deleted eventually, no matter what happens.

Split up util.cpp/h into:
- string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach)
- money utilities (parsesmoney, formatmoney)
- time utilities (gettime*, sleep, format date):
- and the rest (logging, argument parsing, config file parsing)
The latter is basically the environment and OS handling,
and is stripped of all utility functions, so we may want to
rename it to something else than util.cpp/h for clarity (Matt suggested
osinterface).
Breaks dependency of sha256.cpp on all the things pulled in by util.
This is the first part of a huge effort to rework the handling of dependencies.
To start, this change allows all supported platforms to build against a static
Qt. 5.2.1 and 5.3 have been successfully tested against osx64, win32, win64,
linux32, and linux64.
It also makes a small change to the windows config, to allow linking against
qt builds with or without built-in libjpeg/libpng/libpcre/libz.
The actual build processes to take advantage of these changes (for gitian and
pull-tester) are coming soon. Until then, this should be a no-op.
Start the core thread only when needed for initialization
or shutdown.
Avoids a bit of overhead, and also avoids spamming two
log messages before logging is properly initialized.
This commit removes all the unnecessary dependencies (key, core,
netbase, sync, ...) from bitcoin-cli.
To do this it shards the chain parameters into BaseParams, which
contains just the RPC port and data directory (as used by utils and
bitcoin-cli) and Params, with the rest.
bitcoin-config.h moved, but the old file is likely to still exist when
reconfiguring or switching branches. This would've caused files to not rebuild
correctly, and other strange problems.
Make the path explicit so that the old one cannot be found.
Core libs use config/bitcoin-config.h.
Libs (like crypto) which don't want access to bitcoin's headers continue
to use -Iconfig and #include bitcoin-config.h.
Adds a `-version` or `--version` option to print just the version
of the program for bitcoind, bitcoin-cli and bitcoin-qt.
Also make it that `-help` can be used to display the help (as well as
existing `--help`). Up to now, `-help` was the only option that didn't
work with either one or two dashes.
The rcc tool is quirky and only honors files in the same directory as the qrc.
When doing an out-of-tree build (as 'make distcheck' does), the generated
translation files end up in a different path, so rcc can't find them.
Split them up so that rcc is run twice: once for static source files and once
for generated files.
- prevents unsafe shutdowns on Windows, which is known to be
able to cause problems with wallet.dat
- if a users ends a Windows session, this will initiate a client shutdown
and show a Windows dialog, that tells the user what is going on (for
Windows Vista and higher it will even show a reason for blocking the
Windows session end)
Changes for the datadir chooser have made it impossible to specify
the network (testnet/regtest) in the configuration file for the GUI.
Reorganize the initialization sequence to make this possible again.
- Moves the "datadir" QSetting so that is no longer dependent on the
network-specific application name (doing otherwise would create a
chicken-and-egg problem).
- Re-initialize translations after choosing network. There may be a
different language configured in network-specific settings
(slim chance, but handle it for sanity).
