… option 707d0de Squashed 'src/ipc/libmultiprocess/' changes from 16bf05dea02..28e056576a3 (Ryan Ofsky) Pull request description: The changes can be verified by running `test/lint/git-subtree-check.sh src/ipc/libmultiprocess` as described in [developer notes](https://github.com/bitcoin/bitcoin/blob/master/doc/developer-notes.md#subtrees) and [lint instructions](https://github.com/bitcoin/bitcoin/tree/master/test/lint#git-subtree-checksh). Change since last subtree update (#35661): - Adds an optional `max_connections` parameter to `ListenConnections` ([#269](bitcoin-core/libmultiprocess#269)) This is needed for #35037 which lets the maximum number of IPC of incoming connections be configured in bitcoin core.

…hreadMap.makePool` method 6b0a907 Squashed 'src/ipc/libmultiprocess/' changes from 3edbe8f67c1..16bf05dea02 (Ryan Ofsky) Pull request description: The changes can be verified by running `test/lint/git-subtree-check.sh src/ipc/libmultiprocess` as described in [developer notes](https://github.com/bitcoin/bitcoin/blob/master/doc/developer-notes.md#subtrees) and [lint instructions](https://github.com/bitcoin/bitcoin/tree/master/test/lint#git-subtree-checksh). Changes since last subtree update (#34977): - Adds `makePool` method on `ThreadMap` to support thread pool routing, allowing requests without a specific client thread to be dispatched to a pool using a shortest-queue strategy ([#283](bitcoin-core/libmultiprocess#283)). - Adds `std::unordered_set` support, a `BuildList` helper, and a `ReadList` helper to reduce duplication in list build and read handlers ([#277](bitcoin-core/libmultiprocess#277), [#285](bitcoin-core/libmultiprocess#285)). - Adds support for translating C++ `std::optional<T>` struct fields to pairs of `T` + `hasT :Bool` Cap'n Proto struct fields, allowing unset optional primitive fields to be represented ([#243](bitcoin-core/libmultiprocess#243)). - Produces more readable log output for Proxy object lifecycle events and IPC server-side failures ([#218](bitcoin-core/libmultiprocess#218)). - Handles exceptions thrown by `destroy` methods by logging instead of aborting ([#273](bitcoin-core/libmultiprocess#273)). This can prevent server crashes when non-libmultiprocess clients disconnect without destroying objects, in the case where a server object owns client objects and the server destructor tries to call the disconnected client to free them ([#219](bitcoin-core/libmultiprocess#219)). - Handles unexpected exceptions thrown by callbacks (that should never happen) by logging errors instead of deadlocking ([#260](bitcoin-core/libmultiprocess#260)). - Fixes a rare mptest hang on musl builds caused by a lost wakeup bug in `Waiter` ([#295](bitcoin-core/libmultiprocess#295)). - Fixes a race condition in a log print detected by TSan ([#286](bitcoin-core/libmultiprocess#286)). - Build improvements: makes `target_capnp_sources` work correctly when libmultiprocess is used as a CMake subproject ([#289](bitcoin-core/libmultiprocess#289)), adds `mp_headers` target for better lint tool support ([#291](bitcoin-core/libmultiprocess#291)), and fixes compatibility with recent Nix and CMake 4.0 ([#238](bitcoin-core/libmultiprocess#238)). - Test, CI, documentation, and minor code improvements: design document corrections ([#278](bitcoin-core/libmultiprocess#278)), field constant comments ([#279](bitcoin-core/libmultiprocess#279)), clang-tidy fix ([#292](bitcoin-core/libmultiprocess#292)), new smoke test for double-precision float values ([#294](bitcoin-core/libmultiprocess#294)), new test for recursive async IPC calls ([#301](bitcoin-core/libmultiprocess#301)), removal of libevent from Core CI builds ([#299](bitcoin-core/libmultiprocess#299)), and rename of `EventLoop::m_num_clients` to `m_num_refs` ([#302](bitcoin-core/libmultiprocess#302)).

makePoolmethod onThreadMapto support thread pool routing, allowing requests without a specific client thread to be dispatched to a pool using a shortest-queue strategy (#283).std::unordered_setsupport, aBuildListhelper, and aReadListhelper to reduce duplication in list build and read handlers (#277, #285).std::optional<T>struct fields to pairs ofT+hasT :BoolCap'n Proto struct fields, allowing unset optional primitive fields to be represented (#243).destroymethods by logging instead of aborting (#273). This can prevent server crashes when non-libmultiprocess clients disconnect without destroying objects, in the case where a server object owns client objects and the server destructor tries to call the disconnected client to free them (#219).Waiter(#295).target_capnp_sourceswork correctly when libmultiprocess is used as a CMake subproject (#289), addsmp_headerstarget for better lint tool support (#291), and fixes compatibility with recent Nix and CMake 4.0 (#238).EventLoop::m_num_clientstom_num_refs(#302).
