multi_index: fix compilation failure with boost >= 1.91

This commit fixes a build failure that occurs when compiling Bitcoin Core with Boost version 1.91 or newer. It changes how certain in-memory data structures (used for tracking orphan transactions, mempool entries, and transaction requests)…

btcsignals: use a single shared_ptr for liveness and callback

This is a small internal code cleanup in Bitcoin Core's custom signal/slot system. It merges two separate shared pointers (one tracking whether a callback is still active, and one used as a construction tag) into a single shared pointer. T…

signals: re-add forward-declares to interface headers

This is a routine code cleanup commit. It replaces a full header include with a simple forward declaration in two interface header files. There is no security-relevant change and no indication of a vulnerability being fixed.

signals: remove boost includes where possible

This is a routine build cleanup. A developer removed two leftover references to the Boost C++ library from the project's build instructions because those parts of the code no longer use Boost. There is no security issue here.

signals: Add a simplified boost-compatible implementation

This commit replaces Bitcoin Core's use of the Boost signals2 library with a new, simplified in-house implementation called btcsignals. It is a code refactoring/reimplementation intended to reduce dependency on Boost. The change itself doe…

signals: remove boost::signals2 mentions in linters and docs

This commit is a routine cleanup of documentation and a linting script. It updates an example in the developer notes to reference the project's own signal library (btcsignals) instead of the old Boost signals2 library, and removes three Bo…

signals: remove boost compatibility guards

This is a small cleanup of a test file. It removes version-specific workarounds for older Boost library versions, keeping only the behavior needed for the newest Boost version. There is no security issue here.

qt: add patch to fix build with gcc16

kernel: avoid potential duplicate object in shared library/binary

This change moves a one-time initialization flag from a header file into a source file. The warning suggested that, because the flag was defined in a header, it could end up duplicated when Bitcoin's kernel library is linked into other pro…
