aaudio: convert mono output to stereo
MMAP hardware streams are often stereo.
But apps often want to output a mono stream.
Since converting from mono to stereo is easy,
we can go ahead and open a stereo hardware stream
and then just convert the apps mono data to stereo for the HW.
Add getDeviceChannelCount().

aaudio: prevent stop/close from a callback
Detect whether AAudioStream_requestStop() is being called
from a data or error callback and return error.
Also for start(), pause(), flush() and close().
Honor AAUDIO_CALLBACK_RESULT_STOP in Legacy callback.

aaudio: use xruns detected in the service
The service knows when an actual xrun occurs so we pass
that value to the client.

aaudio: cleanup logs and comments
This CL should not change any code behavior except for log text.
Mostly it removes redundant class names from the log.

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.

aaudio: fix CTS for MMAP mode
Improve calculation of buffer capacity based on requested minimum.
Adjust timing of start() to reduce underflows.
Track ServiceEndpoints based on requested deviceId.
Fix getFramesRead() and flush() behavior.
Fix timeouts due to ClockModel lateness bug.
Misc cleanup.
