dax 9d65f39d52 Added support for changing the volume of AudioTrack as discussed in BUG=webrtc:6533
This is a short term solution to change the volume of an AudioTrack until applyConstraints for MediaStreamTracks has been implemented.

This CL adds 1 new Java method & the relevant JNI file update:

AudioTrack.java:

public void setVolume(double volume);
