This reverts ee7b84e63cbeadd5e680d69ff0548275581e9241 from #20527.
This change was made without any rationale, maybe other than a brew
installed version might be newer, and that's "better". However when
building from source on macOS, it just results in drastically worse
perofrmance, and results in issues / confusions like #25724.
Resolves the "build from source" portion of #25724. Building from
depends is still not ideal, however I have some other changes that might
help improve things in that case.
The difference in performance can be observed using the example from
https://github.com/bitcoin/bitcoin/issues/25724#issuecomment-1213554922,
but minified to only 10 descriptors. i.e:
```bash

Running master, when building from souce and using brew installed
sqlite, this takes ~3.4s. With this PR, the same operation takes ~0.3s.

`crc32c`'s hardware accelerated code doesn't handle ARM 32-bit at all.
Make the check in `configure.ac` check for this architecture explicitly.
For the release binaries, the current `configure.ac` check happens
to work: it enables it on aarch64 but disables it for armhf. However
some combination of compiler version and settings might ostensibly cause
this check to succeed on armhf (as reported on IRC). So make the 64-bit
platform requirement explicit.

These tests are failing when run against OpenSSL 3, and have been
removed upstream, https://github.com/bitcoin-core/secp256k1/pull/983, so
disabled them for now to avoid `make check` failures.
Note that this will also remove warning output from our build, due to
the use of deprecated OpenSSL API functions. See #23048.

8f7704d0321a71c1691837a6bd3b4e05f84d3031 build: improve detection of eBPF support (fanquake)
Pull request description:
Just checking for the `sys/sdt.h` header isn't enough, as systems like macOS have the header, but it doesn't actually have the `DTRACE_PROBE*` probes, which leads to [compile failures](https://github.com/bitcoin/bitcoin/pull/22006#issuecomment-859559004). The contents of `sys/sdt.h` in the macOS SDK is:
```bash
#ifndef _SYS_SDT_H
#define _SYS_SDT_H
/*
* This is a wrapper header that wraps the mach visible sdt.h header so that
* the header file ends up visible where software expects it to be. We also
* do the C/C++ symbol wrapping here, since Mach headers are technically C
* interfaces.
*
* Note: The process of adding USDT probes to code is slightly different
* than documented in the "Solaris Dynamic Tracing Guide".
* The DTRACE_PROBE*() macros are not supported on Mac OS X -- instead see
* "BUILDING CODE CONTAINING USDT PROBES" in the dtrace(1) manpage
*
*/
#include <sys/cdefs.h>
__BEGIN_DECLS
#include <mach/sdt.h>
__END_DECLS
#endif /* _SYS_SDT_H */
```
The `BUILDING CODE CONTAINING USDT PROBES` section from the dtrace manpage is available [here](https://gist.github.com/fanquake/e56c9866d53b326646d04ab43a8df9e2), and outlines the more involved process of using USDT probes on macOS.

Pull request description:
This follows the introduction of GUI support in https://github.com/bitcoin-core/gui/pull/4
I don't think we should expect GUI users to self compile. This also enables external signer support by default for RPC users.
In addition this PR reduces the number of `#ifdef ENABLE_EXTERNAL_SIGNER`, which also fixes #21919. When compiled with `--disable-external-signer` such wallets can't be created in RPC or GUI, but they can be loaded. Attempting any action that calls HWI will trigger an error.
Side-note: this PR may or may not (currently) break CI for the GUI repository, as explained here: https://github.com/bitcoin-core/gui/pull/4#issuecomment-769859001

I suppose, that Apple clang-1205.0.22.9 ends with on of the "Revert..." commits.
This PR prevents using of the `-fstack-clash-protection` flag if it causes warnings.

When building with Clang, if `-fstack-clash-protection` is used with an
unsupported target, it may result in hundreds of
`-Wunused-command-line-argument` warnings at compile time. This is
currently the case when building for at least Darwin using Apple or LLVM
Clang.
Unsupported targets may also include *BSD, however that is changing; see
further discussion in https://reviews.llvm.org/D92245 and
https://reviews.freebsd.org/D27366.
Note that this option is already skipped for Windows.

a5491882a06d3bf7c486033037edd9c9203ecaed build: fix configuring when building depends with NO_BDB=1 (fanquake)
Pull request description:
Currently, if you build depends using `NO_BDB=1` (only sqlite wallets), `./configure` will fail as it still tries to find bdb. i.e:
```bash
make -C depends/ NO_QT=1 NO_BDB=1 NO_UPNP=1 NO_ZMQ=1 NO_NATPMP=1 -j8
...
copying packages: native_b2 boost libevent sqlite
./autogen.sh
./configure --prefix=/home/ubuntu/bitcoin/depends/x86_64-pc-linux-gnu
...
checking for Berkeley DB C++ headers... default
configure: error: Found Berkeley DB other than 4.8, required for portable BDB wallets (--with-incompatible-bdb to ignore or --without-bdb to disable BDB wallet support)
```
This PR fixes the build such that you can build depends, opting out of bdb, without opting out of wallets entirely, and still configure successfully. I think I've tested across most potential configurations. i.e:
```bash
./configure (bdb and sqlite on system)
bdb & sqlite are both are available
./configure --without-bdb (bdb and sqlite on system)
only sqlite
./configure --without-sqlite (bdb and sqlite on system)
only bdb
./configure --disable-wallet (bdb and sqlite on system)
neither bdb or sqlite
depends NO_WALLET=1
./configure --prefix=/bitcoin/depends/x86_64-apple-darwin19.6.0
neither bdb or sqlite
depends NO_BDB=1
./configure --prefix=/bitcoin/depends/x86_64-apple-darwin19.6.0

7abac98d3e3c1bc8ad66cb5c05184b9c5cc674d5 configure: Support -f{debug,macro}-prefix-map (Anthony Towns)
Pull request description:
When bitcoin is checked out in two directories (eg via git worktree) object files between the two will differ due to the full path being included in the debug section. `-fdebug-prefix-map` is used to replace this with "." to avoid this unnecessary difference and allow ccache to share objects between worktrees (provided the source and compile options are the same).
Also provide `-fmacro-prefix-map` if supported so that the working dir is not encoded in `__FILE__` macros.

The register keyword was deprecated in C++11, and removed in C++17. Now
that we require C++17, we shouldn't have to supress warnings for a
non-existant feature.

ebfb10cb75adb704418d08197681c1e742e63bd5 Qt: add Android packaging support (Igor Cota)
Pull request description:
This PR is the third and final piece of the basic Android support puzzle - it depends on https://github.com/bitcoin/bitcoin/pull/16110 and is related to https://github.com/bitcoin/bitcoin/pull/16883. It introduces an `android` directory under `qt` and a simple way to build an Android package of `bitcoin-qt`:
1. Build depends for Android as described in the [README](https://github.com/bitcoin/bitcoin/blob/master/depends/README.md)
2. Configure with one of the resulting prefixes
3. Run `make && make apk` in `src/qt`
The resulting APK files will be in `android/build/outputs/apk`. You can install them manually or with [adb](https://developer.android.com/studio/command-line/adb). One can also open the `android` directory in Android Studio for that integrated development and debugging experience. `BitcoinQtActivity` is your starting point.
Under the hood makefile `apk` target:
1. Renames the `bitcoin-qt` binary to `libbitcoin-qt.so` and copies it over to a folder under `android/libs` depending on which prefix and corresponding [ABI](https://developer.android.com/ndk/guides/abis.html#sa) `bitcoin-qt` was built for
2. Takes `libc++_shared.so` from the Android NDK and puts in the same place. It [must be included](https://developer.android.com/ndk/guides/cpp-support) in the APK
3. Extracts Qt for Android Java support files from the `qtbase` archive in `depends/sources` to `android/src`
There is also just a tiny bit of `ifdef`'d code to make the Qt Widgets menus usable. It's not pretty but it works and is a stepping stone towards https://github.com/bitcoin/bitcoin/pull/16883.

Introduce an android directory under qt and allow one to package bitcoin-qt for Android by running make apk.
Add bitcoin-qt Android build instructions.

This has never worked with any of the mingw-w64 compilers we use, and
the -O0 is causing issues for builders applying spectre mitigations.
Recent discussion on https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90458
also indicates that this should just not be used on Windows.

e017a913d0d78ef0766cf73586fe7a38488e1a26 bitcoind: Add -daemonwait option to wait for initialization (Wladimir J. van der Laan)
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.

This fixes linking issues and mirrors what we do with miniupnpc.

This change fixes an error when the value of the "use_boost" variable is
equal to "no".

This makes easier to spot conditional macros.

Pull request description:
Split out two renames from #21003:
* `PROVIDE_FUZZ_MAIN_FUNCTION`. *Reason*: This in only used by fuzzing, so the name should indicate that.
* `MakeNoLogFileContext`. *Reason*: Better reflects what the helper does. Also, prepares it to be used in non-fuzz tests in the future.

9bac71350d98580cc7441957fc7c3fa2f4158553 build: make HAVE_O_CLOEXEC available outside LevelDB (bugfix) (Sebastian Falbesoner)
584fd91d2d294883e6896dbd64a2176528e94581 init: only use pipe2 if availabile, check in configure (Sebastian Falbesoner)
Pull request description:
The result of the O_CLOEXEC availability check is currently only set in the Makefile and passed to LevelDB (see `LEVELDB_CPPFLAGS_INT` in `src/Makefile.leveldb.include`), but not defined to be used in our codebase. This means that code within the preprocessor conditional `#if HAVE_O_CLOEXEC` was actually never compiled. On the master branch this is currently used for pipe creation in `src/shutdown.cpp`, PR #21007 moves this part to a new module (I found the issue while testing that PR).
The fix is similar to the one in #19803, which solved the same problem for HAVE_FDATASYNC.
In the course of working on the PR it turned out that pipe2 is not available an all platforms, hence a configure check and a corresponding define HAVE_PIPE2 is introduced and used.
The PR can be tested by anyone with a system that has pipe2 and O_CLOEXEC available by putting gibberish into the HAVE_O_CLOEXEC block: on master, everything should compile fine, on PR, the compiler should abort with an error. At least that's my naive way of testing preprocessor logic, happy to hear more sophisticated ways :-)
