MeidaPlayerGlue: Fix unable to play music, ...

... Playback state loss problem in Activity.onStop, and
leaking in enableProgressUpdate.

1. MediaPlayerGlue enableProgressUpdate() does not remove
previous Runnable, causing a leak.

2. MediaPlayerGlue.setMediaSource() does not call
prepareMediaForPlaying() and the prepare is relying on
SurfaceCreated being called. So it fails to play music.

3. onSurfaceDestroy/onSurfaceCreate should not reset player
which causing state loss in activity onStop().
