c3e6fdee6d39d3f52dec421b48a0ac8bad5006f7 shutdown: Use RAII TokenPipe in shutdown (Wladimir J. van der Laan)
612f746a8ffa265b6877bedbbe21fcbb392f1516 util: Add RAII TokenPipe (Wladimir J. van der Laan)
Pull request description:
This adds a `-daemonwait` flag that does the same as `-daemon` except that it, from a user perspective, backgrounds the process only after initialization is complete. This is similar to the behaviour of some other software such as c-lightning.
This can be useful when the process launching bitcoind wants to guarantee that either the RPC server is running, or that initialization failed, before continuing. The exit code indicates the initialization result.
The use of the libc function `daemon()` is replaced by a custom implementation which is inspired by the [glibc implementation](https://github.com/lattera/glibc/blob/master/misc/daemon.c#L44), but which also creates a pipe from the child to the parent process for communication.
An additional advantage of having our own `daemon()` implementation is that no MACOS-specific pragmas are needed anymore to silence a deprecation warning.
TODO:
- [x] Factor out `token_read` and `token_write` to an utility, and use them in `shutdown.cpp` as well—this is exactly the same kind of communication mechanism.
- [x] RAII-ify pipe endpoints.
- [x] Improve granularity of the `configure.ac` checks. This currently still checks for the function `daemon()` which makes no sense as it's not used. It should check for individual functions such as
`fork()` and `setsid()` etc—the former being required, the second optional.
- [-] ~~Signal propagation during initialization: if say, pressing Ctrl-C during `-daemonwait` it would be good to pass this SIGINT on to the child process instead of detaching the parent process and letting the child run free.~~ This is not necessary, see https://github.com/bitcoin/bitcoin/pull/21007#issuecomment-769007341.
Future:
- Consider if it makes sense to use this in the RPC tests (there would be no more need for "is RPC ready" polling loops). I think this is out of scope for this PR.

cc61bc2e19b1c8cb32778ef42746d32b02cc2671 compat: remove glibcxx sanity checks (fanquake)
Pull request description:
These checks were added in #4339, (see also #4081), to test
our back-compat stubs, however, those stubs no-longer exist (#22930),
meaning that these checks are now just testing some specific standard
library behaviour, without a particular rationale, or reason, compared
to any other standard library functionlity we use.
There has also been some discussion about our sanity checks in the
context of the libbitcoinkernel refactoring, see https://github.com/bitcoin/bitcoin/pull/25065#discussion_r880668218.
Removing the checks removes the need to worry about atleast the
glibcxx checks.
Also remove the list of checks from the doc in `init.h`, because it is
incomplete, and anyone who wants to know what checks are included can
look at the function.

Pull request description:
When writing tests, often includes need to be added or removed. Currently the list of includes is not sorted, so developers that write tests and have `clang-format` installed will either have an unrelated change (sorting) included in their commit or they will have to manually undo the sort.
This pull preempts both issues by just sorting all includes in one commit.
Please be aware that this is **NOT** a change to policy to enforce clang-format or any other developer guideline or process. Developers are free to use whatever tool they want, see also #18651.
Edit: Also includes a commit to bump the copyright headers, so that the touched files don't need to be touched again for that.

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.

- *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
- ensures a consistent usage in header files
- also add a blank line after the copyright header where missing
- also remove orphan new-lines at the end of some files
Adds a copyright and attribution message to the `-version` output
(the same as shown in the About dialog in the GUI).
Move the message to a function LicenseInfo in init.cpp.
Allow running bitcoind without server.
- Default to -server mode (of course) for bitcoind with SoftSetBoolArg
- Remove fForceServer argument from AppInit2
- Move fDaemon to a static variable in bitcoind
Remove unnecessary dependencies for bitcoin-cli
(leveldb, berkelydb, wallet, RPC server)
Build system changes:
- split libbitcoin.a into libbitcoin_common.a, libbitcoin_server.a and
libbitcoin_cli.a
Code changes (movement only):
- split up HelpMessage into HelpMessage in init.cpp and HelpMessageCli
in rpcclient.cpp
- move uiInterface from init.cpp to util.cpp
Use misc methods of avoiding unnecesary header includes.
Replace int typedefs with int##_t from stdint.h.
Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h.
Normalize QT_VERSION ifs where possible.
Resolve some indirect dependencies as direct ones.
Remove extern declarations from .cpp files.
This required some code movement (what was CWalletTx::AcceptToMemoryPool
doing in main?), and adding a few explicit includes that used to be
implicit through init.h.
