Add the necessary helpers in GstVaapiDisplay to determine whether subpictures
with global alpha are supported or not. Also add accessors in GstVaapiSubpicture
to address this feature.

Align gst_vaapi_decoder_get_surface() semantics with the rest of the
API. That is, return a GstVaapiDecoderStatus and the decoded surface
as a handle to GstVaapiSurfaceProxy in parameter.
This is an API/ABI change.
GstVaapiSurfaceProxy does not use any particular functionality from
GObject. Actually, it only needs a basic object type with reference
counting.
This is an API and ABI change.
GStreamer codecparsers-based decoders are the only supported decoders now.
Though, FFmpeg decoders are still available in gstreamer-vaapi 0.3.x series.
