Compiling bdb with clang-16 on aarch64 (hardware) currently fails:

Clang-16 changed `-Wimplicit-function-declaration` and `-Wimplicit-int`
warnings into errors, see:

Reasonably enough I guess, it appears that a number of our dependencies block github runner IP addresses? the blobs stored at the s3 link were downloadable from the normal location when accessed locally, but returned a 404 from github runners. These blobs were also not present in the bitcoincore depends-sources anyhow.

Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
---
This PR adds basic process spawning and IPC method call support to `bitcoin-node` executables built with `--enable-multiprocess`[*].
These changes are used in https://github.com/bitcoin/bitcoin/pull/10102 to let node, gui, and wallet functionality run in different processes, and extended in https://github.com/bitcoin/bitcoin/pull/19460 and https://github.com/bitcoin/bitcoin/pull/19461 after that to allow gui and wallet processes to be started and stopped independently and connect to the node over a socket.
These changes can also be used to implement new functionality outside the `bitcoin-node` process like external indexes or pluggable transports (https://github.com/bitcoin/bitcoin/pull/18988). The `Ipc::spawnProcess` and `Ipc::serveProcess` methods added here are entry points for spawning a child process and serving a parent process, and being able to make bidirectional, multithreaded method calls between the processes. A simple example of this is implemented in commit "Add echoipc RPC method and test."
Changes in this PR aside from the echo test were originally part of #10102, but have been split and moved here for easier review, and so they can be used for other applications like external plugins.
Additional notes about this PR can be found at https://bitcoincore.reviews/19160
[*] Note: the `--enable-multiprocess` feature is still experimental, and not enabled by default, and not yet supported on windows. More information can be found in [doc/multiprocess.md](https://github.com/bitcoin/bitcoin/blob/master/doc/multiprocess.md)

148b33cf72033eced8a701d127e21dfe8a816ce3 build: Replace `which` command with `command -v` (Hennadii Stepanov)
Pull request description:
On some systems the `which` command can emit messages into stderr. For example, for `debianutils 5.5-1` package in Debian Sid:
```
# which cat
/usr/bin/which: this version of `which' is deprecated; use `command -v' in scripts instead.
/bin/cat
```
Although such messages are harmless, they could distract developers needlessly (see bitcoin/bitcoin#24056).

Old version doesn't support debug information for ELF produced by modern compilers
It appears like an error:
> unrecognized DWARF version in .debug_info at 6
> no debug info in ELF executable
which causes:
> No debug information available for stacktrace. You should add debug information and then run
And backtraces are not shown on linux even if debug infos here.

Hope, this PR will make [transit](https://github.com/bitcoin/bitcoin/pull/21376) to Qt 5.12.10 neater.

[QTBUG-34748](https://bugreports.qt.io/browse/QTBUG-34748) was [fixed](b19b080894) in Qt 5.3.0.
The separated [`fix-xcb-include-order.patch`](bb44d9e754/depends/patches/qt/fix-xcb-include-order.patch), provided by #5915, was dropped in #12971 while bumping Qt to 5.9.4 (5.9.6). But `libxcb.mk` remained unchanged.
This PR reverts #5915 for `libxcb.mk` as well.

e838a9847580527b8321d65e57b1c53cc2af6bf4 depends: re-enable using -flto when building expat (fanquake)
304452558c7f6f5e32ba13d8f05325790c8a4f5f depends: expat 2.4.8 (fanquake)
Pull request description:
Currently, when building the expat package in depends, using `-flto` (`LTO=1`), the configure check can fail, because it cannot determine the system endianess:
```bash
configure:18718: result: unknown
configure:18733: error: unknown endianness
presetting ac_cv_c_bigendian=no (or yes) will help
```
Fix that by defining `_DEFAULT_SOURCE`, which in turn defines `__USE_MISC` (`features.h`):
```c
#if defined _DEFAULT_SOURCE
# define __USE_MISC1
#endif
```
which exposes additional definitions in `endian.h`:
```c
#include <features.h>
/* Get the definitions of __*_ENDIAN, __BYTE_ORDER, and __FLOAT_WORD_ORDER. */
#include <bits/endian.h>
#ifdef __USE_MISC
# define LITTLE_ENDIAN__LITTLE_ENDIAN
# define BIG_ENDIAN__BIG_ENDIAN
# define PDP_ENDIAN__PDP_ENDIAN
# define BYTE_ORDER__BYTE_ORDER
#endif
```
and gives us a working configure.
You could test building this change with Guix + LTO with [this branch](https://github.com/fanquake/bitcoin/tree/lto_in_guix). Note that that build may fail for other reasons (on x86_64), unrelated to this change.

c0f5cc14ef9fae2b2de4222ee061729629ebb6b4 build: Fix `libmultiprocess` cross-compiling to Linux hosts (Hennadii Stepanov)
Pull request description:
To successfully call the [`capnp_generate_cpp()`](d576d975de/CMakeLists.txt (L45)) function, the `libmultiprocess` build system must be provided with paths to the native `capnp` and `capnpc-c++` tools.
This [comment](https://github.com/bitcoin/bitcoin/issues/24387#issuecomment-1054776195) points the same:
> I think `packages/libmultiprocess.mk` probably needs to be passing a `-DCAPNP_EXECUTABLE=.../depends/arm-linux-gnueabihf/native/bin/capnp` argument to cmake. Also the package should have dependencies on both `capnp` and `native_capnp`.

No source or binary directory provided. Both will be assumed to be the
same as the current working directory, but note that this warning will
become a fatal error in future CMake releases.
```
It's unclear if this will actually ever become an error, but it's also easy
enough to just supply the directory, and save this maybe breaking in
future.

Code review ACK 7c218dacd0e9602b8f755be42e96c49706f96305. I guess the purpose of the warning is to encourage people not to build in the source directory, but reasons for encouraging this don't really apply to the depends build system, so it is appropriate to disable the warning.

This PR fixesbitcoin/bitcoin#24389.
On master (28aa0e3ca0a6cfeb5b2b63929d4bc58de6ee6f02) configuring of the `libmultiprocess` package for the `x86_64-w64-mingw32` target fails:

The reason of that failure is the unset `-DCMAKE_SYSTEM_NAME` flag:
```

01e121d29087db047e4bc01bd64d054f83cfc5df depends: fix capnp's descriptor for make download (Cory Fields)
Pull request description:
The non-native capnp was trying to fetch the wrong file.
Without this, "make -C depends MULTIPROCESS=1 download" is broken.
Presumably it breaks with the download target because the dependency graph is flattened. It manages to work if native_capnp is encountered first because it will then be found in the cache.

735610940c0cac72343ca247eb3062b2e09512a0 build: set --build when configuring packages in depends (fanquake)
Pull request description:
After reading [#Specifying-Target-Triplets](https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.69/autoconf.html#Specifying-Target-Triplets) in the autoconf manuel, my understanding is that this change should mostly be a no-op, as `--build` defaults to the output of [`config.guess`](https://github.com/bitcoin/bitcoin/blob/master/depends/config.guess), however, this may be slightly more correct
> For historical reasons, whenever you specify --host, be sure to specify --build too; this will be fixed in the future.
and will quell some warnings in depends (#16354), i.e:
> configure: WARNING: If you wanted to set the --build type, don't use --host.
If a cross compiler is detected then cross compile mode will be used.
If anything, this also explicitly enables cross-compilation mode when `--host` differs from `--build`. As for "fixed in the future", this is the case for Autoconf 2.70+.
If we don't make this change, I think we should consider closing #16354. We've now got a good handle on our depends configure flags, and we can just leave the last few warnings as they are. It's also unlikely that we are going to add the `xorg-macros` package to depends.

7d0271b5c30f86e4af175a5ab7df5e593cd85195 depends: Set CMAKE_INSTALL_RPATH for native packages (Russell Yanofsky)
Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
---
After #19685 started setting `LDFLAGS`, the `INSTALL_RPATH_USE_LINK_PATH` cmake option used in the libmultiprocess build no longer works, so it is neccessary to set `CMAKE_INSTALL_RPATH` as a fallback.
It's unclear currently whether the bad interaction between `INSTALL_RPATH_USE_LINK_PATH` and `LDFLAGS` is a bug, but the issue is reported:

ACK 7d0271b Looked into this a bit, it makes sense that for the things we build in depends, we want the library search to start in depends. It seems reasonable to expect this to happen automatically when `CMAKE_INSTALL_PREFIX` and `INSTALL_RPATH_USE_LINK_PATH` are set, but oh well...

Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
---
This PR consists of build changes only. It adds an `--enable-multiprocess` autoconf option (off by default and marked experimental), that builds new `bitcoin-node` and `bitcoin-gui` binaries. These currently function the same as existing `bitcoind` and `bitcoin-qt` binaries, but are extended in #10102 with IPC features to execute node, wallet, and gui functions in separate processes.
In addition to adding the `--enable-multiprocess` config flag, it also adds a depends package and autoconf rules to build with the [libmultiprocess](https://github.com/chaincodelabs/libmultiprocess) library, and it adds new travis configuration to exercise the build code and run functional tests with the new binaries.
The changes in this PR were originally part of #10102 but were moved into #16367 to be able to develop and review the multiprocess build changes independently of the code changes. #16367 was briefly merged and then reverted in #18588. Only change since #16367 has been dropping the `native_boost.mk` depends package which was pointed out to be no longer necessary in https://github.com/bitcoin/bitcoin/pull/16367#issuecomment-596484337 and https://github.com/bitcoin/bitcoin/pull/18588#pullrequestreview-391765649

8e55981ef834490c438436719f95cbaf888c4914 refactor: replace Boost shared_mutex with std shared_mutex in cuckoocache tests (fanquake)
Pull request description:
This replaces `boost::shared_mutex` and `boost::unique_lock` with [`std::shared_mutex`](https://en.cppreference.com/w/cpp/thread/shared_mutex) & [`std::unique_lock`](https://en.cppreference.com/w/cpp/thread/unique_lock).
Even though [some concerns were raised](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-726214696) in #16684 with regard to `std::shared_mutex` being unsafe to use across some glibc versions, I still think this change is an improvement. As I mentioned in #21022, I also think trying to restrict standard library feature usage based on bugs in glibc is not only hard to do, but it's not currently clear exactly how we do that in practice (does it also extend to patching out use in our dependencies, should we be implementing more runtime checks for features we are using, when do we consider an affected glibc "old enough" not to worry about? etc). If you take a look through the [glibc bug tracker](https://sourceware.org/bugzilla/describecomponents.cgi?product=glibc) you'll no doubt find plenty of (active) bug reports for standard library code we already using. Obviously not to say we shouldn't try and avoid buggy code where possible.
Two other points:
[Cory mentioned in #21022](https://github.com/bitcoin/bitcoin/pull/21022#issuecomment-769274179):
> It also seems reasonable to me to worry that boost hits the same underlying glibc bug, and we've just not happened to trigger the right conditions yet.
Moving away from Boost to the standard library also removes the potential for differences related to Boosts configuration. Boost has multiple versions of `shared_mutex`, and what you end up using, and what it's backed by depends on:
* The version of Boost.
* The platform you're building for.
* Which version of `BOOST_THREAD_VERSION` is defined: (2,3,4 or 5) default=2. (see [here](https://www.boost.org/doc/libs/1_70_0/doc/html/thread/build.html#thread.build.configuration) for some of the differences).
* Is `BOOST_THREAD_V2_SHARED_MUTEX` defined? (not by default). If so, you might get the ["less performant, but more robust"](https://github.com/boostorg/thread/issues/230#issuecomment-475937761) version of `shared_mutex`.
A lot of these factors are eliminated by our use of depends, but users will have varying configurations. It's also not inconceivable to think that a distro, or some package manager might start defining something like `BOOST_THREAD_VERSION=3`. Boost tried to change the default from 2 to 3 at one point.
With this change, we no longer use Boost Thread, so this PR also removes it from depends, the build system, CI etc.

Pull request description:
Since v4.3.3 (068385c951) `libzmq` uses `libbsd` by default.
This PR disables `libbsd` explicitly, as it's not a part of our depends. Zeromq will fallback to its internal `strlcpy` implementation.
Otherwise, on systems with installed `libbsd-dev` package the `zeromq` package build system erroneously detects `libbsd` package from the host system:
```diff

Libs: -L${libdir} -lzmq

This causes the `configure` fails to detect the `zeromq` package:
```

```
---
Other minor improvements:
- fixed `netbsd_kevent_void.patch` offset
- disabled valgrind as it's used in unit tests which we do not run:
