Subject: Bug 1972995 - Tag webrtc invocables with location when wrapping them
as runnables. r=bwc,mjf
This does mainly two things:
- Overrides webrtc::Location with a new class declaration in libwebrtcglue,
that makes use of __builtin_FUNCTION et al. on supported toolchains.
- Uses the new location info to construct a better name (through nsINamed) to
tag invocable-wrapped runnables with, for visibility in the profiler.
