libretroadmin 85e45d084f Lock-free DSP thread on libretro-common; trim libretro-common ...

The threaded DSP takes no mutex or condition variable. The emulation
thread publishes a monotonic tick count with a release store and wakes
the DSP thread through a retro_eventcount once per 32 ticks and at
frame end; the DSP thread runs every posted tick and writes samples
into a retro_spsc ring that upload hands to the frontend in place.
Mode switches keep samples in order, and the thread runs out every
posted tick before it exits. THREADED_DSP defines HAVE_THREADS and
builds the eventcount and SPSC sources.

libretro-common is synced with RetroArch master and holds only the
sources the core builds and the headers they and the core include;
rstrtod.c is built since file_stream needs it.
