Fix deadlock with an AudioPlayer playing from a PCM buffer queue.
This type of player uses an AudioTrack that pulls data through
its callback from a buffer queue.
This issue is that when you destroy the player (whick locks the
object), it tries to destroy the AudioTrack object. The
AudioTrack destructor can only finish when the AudioTrack
callback thread can exit. If a callback was underway when
trying to destroy the object, a race condition existed for
the AudioPlayer lock.
The fix consists in using the "pre-destroy" hook for the AudioPlayer
object. In it, we unlock the AudioPlayer, and block until the
AudioTrack callback has signaled it's done. The pre-destroy
hook also marks the track as "about to be destroyed" so any
callback that gets called once the pre-destroy hook has been
called can return immediately.

Created a new audio player class, APlayer, from which we derive
subclasses to encapsulate OpenSL ES AudioPlayer implementations:
- ASfPlayer derives from APlayer and encapsulates StageFright
functionality for audio decoding to a buffer
- ADecoder derives from ASfPlayer and encapsulates rendering
the decoded audio data to a callback function. It interfaces
with the OpenSL ES Buffer Queue interface to pass the decoded
data back to an OpenSL ES application.

For OpenSL ES, to support decoding to a Buffer Queue, we now
allow an AudioPlayer to have its sink be a PCM buffer queue.

The JNI naming conventions avoid conflict with C++ reserved words.
