Squashed 'external/toxcore/c-toxcore/' changes from 1701691d5..640e6cace

640e6cace fix(toxav): remove extra copy of video frame on encode Tested and works, but there might be alignment issues and other stuff.
6f7f51554 chore(toxav): use realtime deadline for vp8 encoder Technically all this does is choose a quality based on frame duration, which we always set to 1, and as such is always realtime. (In same timebase as pts, which we use as a frame counter...)
5047ae5a2 chore: make the source tarball exhibit the old behavior
14804a4b8 chore: Fix sonar-scan CI action.
e2db7d946 cleanup: Exclude lan_discovery test from running on macos, instead of excluding it from the project.
3accade67 chore: Fix CI, disabling some tests that no longer run on CI.
ef8d767e6 cleanup: Fix comment formatting errors.
34ec822da cleanup: Fix some clang-19 format warnings.
40b3f0b46 refactor: Use clang's nullability qualifiers instead of attributes.
f81e30679 refactor: Use per-parameter nullability annotations.
