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.
Fix reference leak of surface and image in GstVaapiVideoBuffer wrapper,
thus resulting on actual memory leak of GstVaapiImage when using them
for downloads/uploads from VA surfaces and more specifically surfaces
when the pipeline is shutdown. i.e. vaTerminate() was never called
because the resources were not unreferenced, and thus not deallocated
in the end.

Introduce new typed constructors internal to gstreamer-vaapi plugin elements.
This avoids duplication of code, and makes it possible to further implement
generic video buffer creation routines that automatically map to base or GLX
variants.
This is a preferred thread-safe version. Also add an inline version of
g_clear_object() if compiling with glib < 2.28.

Allow rendering flags, as a combination of GstVaapiSurfaceRenderFlags,
to be set to the video buffer. In particular, this is mostly useful for
basic deinterlacing.
Add helper function to bind a foreign buffer into a GstVaapiVideoBuffer.
Any image, surface or surface proxy will be inherited from the source buffer
if it is a GstVaapiVideoBuffer.
