Connect MediaRecorder Native to SurfaceMediaSource

Making a connection from MediaRecorder Native layer to the
SurfaceMediaSource for the purpose of encoding GL Frames. This will be
called from the java side inside the Mobile Filter Framework.

The mediarecorder native layer (client), when set the videosource to
option VIDEO_SOURCE_FRAMES, asks the StageFrightRecorder on the mediaserver
side to create a SurfaceMediaSource object and pass it back as a
sp<ISurfaceTexture> object. Using that, the client side will dequeue and
queue buffers. Connecting the GL Frames to the obtained
sp<ISurfaceTexture> is not part of this CL.
