Pull request description:
Broken out of #30454 . Bumped [even further](4883197abc (r1684802528)) after https://github.com/chaincodelabs/libmultiprocess/pull/98 was merged upstream.
hebasto Presumably this approach works now with the CMake branch?

3333f14efac815ba3c885398a6795c7e8ce68d08 depends: Bump to capnproto-c++-1.0.1 (MarcoFalke)
Pull request description:
Reasons:
* Debian is starting to ship this version in Trixie (https://packages.debian.org/trixie/capnproto), which will likely become the version shipped with Ubuntu 24.04 LTS. So testing with this version will help to find any issues before real users start to use those distro packages.
* The feature is currently experimental, so bumping the version shouldn't cause any production issues.
* With multiprocess begin a priority project for 27.0, it seems better to do build system changes/bumps early, rather than later, to allow for more time testing them.

ACK 3333f14efac815ba3c885398a6795c7e8ce68d08 - the response from upstream is that [if we submit a PR, they can take a look](https://github.com/capnproto/capnproto/issues/1833#issuecomment-1792582206), so if anyone would like this to work for Windows, I'd suggest sending a patch.

---
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)

7c218dacd0e9602b8f755be42e96c49706f96305 build: specify cmake build dir for multiprocess depends build (fanquake)
Pull request description:
When no build dir is specified, cmake will warn:
```bash
Preprocessing libmultiprocess...
Configuring libmultiprocess...
CMake Warning:
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.

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
