Add more attributes for raw decoding modes, i.e. directly through the
libgstvaapi helper library. In particular, add presentation timestamp,
duration and a couple of flags (interlaced, TFF, RFF, one-field).
Drop the following functions that are now obsolete:
- gst_vaapi_context_get_surface()
- gst_vaapi_context_put_surface()
- gst_vaapi_context_find_surface_by_id()
- gst_vaapi_surface_proxy_new()
- gst_vaapi_surface_proxy_get_context()
- gst_vaapi_surface_proxy_set_context()
- gst_vaapi_surface_proxy_set_surface()
This is an API change.
Introduce gst_vaapi_surface_proxy_new_from_pool() to allocate a new surface
proxy from the context surface pool. This change also makes sure to retain
the parent surface pool in the proxy.
Besides, it was also totally useless to attach/detach parent context to
VA surface each time we acquire/release it. Since the whole context owns
all associated VA surfaces, we can mark this as such only once and for all.
Move GstVaapiVideoMeta from core libgstvaapi decoding library to the
actual plugin elements. That's only useful there. Also inline reference
counting code from GstVaapiMiniObject.
GStreamer codecparsers-based decoders are the only supported decoders now.
Though, FFmpeg decoders are still available in gstreamer-vaapi 0.3.x series.
Also do not generate tamplate files as all the documentation is inline.
Drop un-needed code in autogen.sh as well.

Allow rendering flags, as a combination of GstVaapiSurfaceRenderFlags,
to be set to the video buffer. In particular, this is mostly useful for
basic deinterlacing.
gst_vaapi_surface_get_parent_context() was not meant to be exposed globally.
It's just an internal helper function. However, it's still possible to get
the parent context through the "parent-context" property.
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.
