Package VideoDecoderGLSurfaceView a little more nicely

Browse Source 
The main change here is that VideoDecoderGLSurfaceView now implements
VideoDecoderOutputBufferRenderer directly. This avoids SimpleExoPlayer
having to cast to VideoDecoderGLSurfaceView, which will be necessary
if VideoDecoderGLSurfaceView is moved to the UI module. Instead, the
player can cast directly to VideoDecoderOutputBufferRenderer, which
could be moved to the Common module.

The renderer is also moved to be an inner class, since it's not used
anywhere else and since doing this makes it a little easier to move
things around.
