timer: remove unnecessary timer thread
This removes the timer thread entirely in favor of a coordinated
delay loop directly within rmdGetFrame.
When there's an audio stream to synchronize with, avd is
maintained by the pcm buffer updates, and the fps-derived
frametimes synchronize with the audio that way.
When there's no audio stream (--no-sound), avd is now maintained
synthetically via clock_gettime(CLOCK_MONOTONIC) coordinating
with the clock instead.
There's been some reworking of frame sampling/reusing and cloning
logic, which may need some refinement. But for now the tests
seem to show promise.
The old timer approach just increased the non-determinism by
adding more scheduler latency and influence unnecessarily.
