Clean up AudioTrack position and timestamp handling
Replace epoch concept by observing and accumulating server delta
positions. The advantage of using server deltas instead of absolute
values is that they (1) are not sensitive to 32-bit wraparound,
(2) are not sensitive to server behavior for stop(), and
(3) prepare for future 64-bit client positions without requiring 64-bit
positions on server.
Add comments to AudioTrack::getTimestamp() and friends
that the timestamp output parameter is undefined on error.
Don't allow getTimestamp to return a negative frame position after stop().
Accumulate the client released frames, which may be useful for a future API.

with dummy default implementation, and implement in MonoPipeReader.
onTimestamp is meant to be called by the corresponding sink when it has
a new timestamp available.

Move libnbaio out of AudioFlinger
libnbaio is now a separate shared library from AudioFlinger, rather
than a static library used only by AudioFlinger.
AudioBufferProvider interface is now also independent of AudioFlinger,
moved to include/media/
