5549dbc3c0 vaapidecode: don't reset decoder if codec type is the same. 
Reset, i.e. destroy then create, the decoder in _setcaps() handler only
if the underlying codec type actually changed. This makes it possible
to be more tolerant with certain MPEG-2 streams that get parsed to
form caps that are compatible with the previous state but minor changes
to "codec-data".

5157a01942 decoder: use g_object_notify_by_pspec(). 
Use g_object_notify_by_pspec() instead of g_object_notify() so that to
avoid a property name lookup. i.e. this makes notifications faster to
the `vaapidecode' element.

7b19745141 decoder: simplify output of decoded frames. 
Drop obsolete gst_vaapi_decoder_push_surface() that was no longer used.
Change gst_vaapi_decoder_push_surface_proxy() semantics to assume PTS
is already set correctly and reference count increased, if necessary.

e5d12e8853 decoder: rework the internal VA objects API. 
The new API simplifies a lot reference counting and makes it more
flexible for future additions/changes. The GstVaapiCodecInfo is
also gone. Rather, new helper macros are provided to allocate
picture, slice and quantization matrix parameter buffers.

3e1d235c1a decoder: fix possible leak of VA surfaces. 
Under some circumstances, we could have leaked a surface, thus not
releasing it to the pool of available surfaces in the VA context.
The strategy is now to use a proxy earlier and automatically ref/unref
whenever necessary. In particular, during the lifetime needed for FFmpeg.
