Simon Farnsworth aafa59f01e vaapidecode: Switch back to Single thread implementation 
Because the decoder uses the thread from handle_frame() to decode a frame,
the src pad task creates an unsolveable AB-BA deadlock between
handle_frame() waiting for a free surface and decode_loop() pushing
decoded frames out.

Instead, have handle_frame() take responsibility for pushing surfaces,
and remove the deadlock completely. If you need a separate thread
downstream, you can insert a queue between vaapidecode and its downstream
to get one.

Another justification for the single thread implementation is,
there are two many point of locking in gstreamer-vaapi's current
implementation which can lead to deadlocks.
