Subject: Initial commit for AudioVideo (com.jogamp.opengl.av) rework,
introducing Android API 14 MediaPlayer impl of GLMediaPlayer.
Android API 14 MediaPlayer allows usage of OMX AL direct decode to texture via libstagefright (OMX AL usage included).
Status: Untested, not working - Need to fix native OMX IL (stream detect and split) and/or GStreamer implementation.
