Initial check-in of variable speed playback library. Contains an implementation of time-domain audio scaler, for pitch-invariant speed up and slow-down of audio. Contains wrapper library using OpenSLES to pump audio from encoded stream (mp3 file etc) through audio decoder then through time scaler and out to media player. This is written as a jni library with jni hooks to allow driving of this from the Java side. The other part of this cl is the Java wrapper. There is a new interface MediaPlayerProxy, containing a subset of the methods found on the MediaPlayer. The VariableSpeed class provides a concrete implementation of this interface adapting to the jni code. Change-Id: I518d8bf703488628c00730241a08ebfb67588ca6
