aaudio: fix timestamps and underruns
Start the client after we get valid timing data from the server.
That can take a while because of the long cold start times.
The client is synced with the current position of the service.
Now the client can start clean with no underruns.

aaudio: reduce glitching by improving sleep timing
ALways sleep a minimum time to avoid busy wait in real-time thread.
Account for wakeup jitter in threads on the other side of a FIFO.
Avoid race condition that caused a longer sleep than necessary.
Fix calculation of mFreeRunning for capture mode.
Also added systrace logging, which was used to debug this.
