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. https://bugzilla.gnome.org/show_bug.cgi?id=703235 Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>

vaapivideocontext: only vaapisink process app context gst.vaapi.app.Display context is made for applications that will provide the VA display and the native display to used by the pipeline, when are using vaapisink as overlay. There are no use case for encoders, decoders, neither for the postprocessor. In the case of the vaapisink, it shall query for gst.vaapi.Display upstream first, and then, if there is no reply, gst.vaapi.app.Display context will be posted in the bus for the application. If the application replies, a GstVaapiDisplay object is instantiated given the context info, otherwise a GstVaapiDisplay is created with the normal algorithm to guess the graphics platform. Either way, the instantiated GstVaapiDisplay is propagated among the pipeline and the have-message bus message. Also only vaapisink will process the gst.vaapi.app.Display, if and only if, it doesn't have a display already set. This is caused because if vaapisink is in a bin (playsink, for example) the need-context is posted twice, leading to an error state. https://bugzilla.gnome.org/show_bug.cgi?id=790999

plugins: check if display is set in sync Since the context messages are sync'ed, the display assignation happens in the same thread, hence we can know if the display was found or not as soon we call for it. In order to take advantage of it, gst_vaapi_video_context_prepare() receives, as a new parameter, the address of the plugin's display, and reports back if the display was found and set.
