Víctor Manuel Jáquez Leal c67b783275 plugins: add compat layer for GstVideoContext.
Add thin compatibility layer for the deprecated GstVideoContext API.
For GStreamer API >= 1.2, this involves the following two functions:
- gst_vaapi_video_context_prepare(): queries if a context is already
  set in the pipeline ;
- gst_vaapi_video_context_propagate(): propagates the newly-created
  context to the rest of the pipeline.
