Bump libmultiprocess library to include bugfix https://github.com/chaincodelabs/libmultiprocess/pull/159 which should fix intermittent CI failures reported in https://github.com/bitcoin/bitcoin/issues/31921 This change is bumping the libmultiprocess version instead of cherry picking the bugfix. It could cherry-pick the bugfix instead, but there are reasons to prefer bumping the version: - Bugfix might interact with earlier PRs, and the latest version is better tested with testing done in many CI configurations in #30975 and #31802 - Even though we are in feature freeze for a release, the MULTIPROCESS=1 option is currently not enabled for release, so this PR only affect CI builds and local builds, not the release build. This update brings in the following changes: https://github.com/chaincodelabs/libmultiprocess/pull/140 build: don't clobber user/superproject c++ version https://github.com/chaincodelabs/libmultiprocess/pull/142 build: add option for external mpgen binary https://github.com/chaincodelabs/libmultiprocess/pull/143 cleanup: initialize vars in the EventLoop constructor in the correct order https://github.com/chaincodelabs/libmultiprocess/pull/146 cmake: Suppress compiler warnings from capnproto headers https://github.com/chaincodelabs/libmultiprocess/pull/147 cmake: EXTERNAL_MPGEN cleanups https://github.com/chaincodelabs/libmultiprocess/pull/148 util: fix -Wpessimizing-move warning https://github.com/chaincodelabs/libmultiprocess/pull/145 CTest: Module must be included at the top level https://github.com/chaincodelabs/libmultiprocess/pull/149 Avoid `-Wundef` compiler warnings https://github.com/chaincodelabs/libmultiprocess/pull/152 refactor: Fix compiler and clang-tidy warnings https://github.com/chaincodelabs/libmultiprocess/pull/155 scripted-diff: s/Libmultiprocess_EXTERNAL_MPGEN/MPGEN_EXECUTABLE/g https://github.com/chaincodelabs/libmultiprocess/pull/156 refactor: Remove locale-dependent function calls https://github.com/chaincodelabs/libmultiprocess/pull/157 refactor: Avoid using std::format https://github.com/chaincodelabs/libmultiprocess/pull/159 bugfix: Do not lock EventLoop::mutex after EventLoop is done https://github.com/chaincodelabs/libmultiprocess/pull/161 cmake: Avoid including CTest if not top level project https://github.com/chaincodelabs/libmultiprocess/pull/164 Bump minimum required cmake to 3.12

What is Bitcoin Core?
Bitcoin Core connects to the Bitcoin peer-to-peer network to download and fully validate blocks and transactions. It also includes a wallet and graphical user interface, which can be optionally built.
Further information about Bitcoin Core is available in the doc folder.
License
Bitcoin Core is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/licenses/MIT.
Development Process
The master branch is regularly built (see doc/build-*.md for instructions) and tested, but it is not guaranteed to be
completely stable. Tags are created
regularly from release branches to indicate new official, stable release versions of Bitcoin Core.
The https://github.com/bitcoin-core/gui repository is used exclusively for the development of the GUI. Its master branch is identical in all monotree repositories. Release branches and tags do not exist, so please do not fork that repository unless it is for development reasons.
The contribution workflow is described in CONTRIBUTING.md and useful hints for developers can be found in doc/developer-notes.md.
Testing
Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.
Automated Testing
Developers are strongly encouraged to write unit tests for new code, and to
submit new unit tests for old code. Unit tests can be compiled and run
(assuming they weren't disabled during the generation of the build system) with: ctest. Further details on running
and extending unit tests can be found in /src/test/README.md.
There are also regression and integration tests, written
in Python.
These tests can be run (if the test dependencies are installed) with: build/test/functional/test_runner.py
(assuming build is your build directory).
The CI (Continuous Integration) systems make sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.
Manual Quality Assurance (QA) Testing
Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.
Translations
Changes to translations as well as new translations can be submitted to Bitcoin Core's Transifex page.
Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works.
Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.
