FEI encoders are not actively mantained neither tested, and it is
using infrastructure that is changing and FEI is stopping this
effort.
Also it is required to rethink how FEI can be used in GStreamer.
GstVaapiMiniObject and GstVaapiObject are deprecated.
This is the first step to remove them by porting GstVaapiSurface as
a GstMiniBuffer descendant.

Add fei codec objects to surface proxy since handling the
fei buffers(codec objects here) external to gstvaapisurfaceproxy
will make the code complicated. Especially considering the behavior
of encoder where the input frame order from upstream and output
frame order to the downstream are not sequential.

Add new GstVaapiSurfaceProxy flag FFB, which means "first frame in
bundle", and really expresses the first view component of a multi
view coded frame. e.g. in H.264 MVC, the surface proxy has flag FFB
set if VOIdx = 0.
Likewise, new API is exposed to retrieve the associated "view-id".
Add gst_vaapi_surface_proxy_copy() function that creates a new surface
proxy with the same information from the parent proxy, except that the
user-defined destroy notify function is not copied over.
The underlying VA surface is pushed back to the video pool only when
the last reference to the parent surface proxy is released.
Make it possible associate an empty cropping rectangle to the surface
proxy, thus resetting any cropping rectangle that was previously set.
This allows for returning plain NULL when no cropping rectangle was
initially set up to the surface proxy, or if it was reset to defaults.
Add gst_vaapi_picture_set_crop_rect() helper function to copy the video
cropping information from raw bitstreams to each picture being decoded.
Also add helper function to surface proxy to propagate that information
outside of libgstvaapi. e.g. plug-in elements or standalone applications.

Drop obsolete GST_VAAPI_IS_xxx() helper macros since we are no longer
deriving from GObject and so those were only checking for whether the
argument was NULL or not. This is now irrelevant, and even confusing
to some extent, because we no longer have type checking.
Note: this incurs more type checking (review) but the libgstvaapi is
rather small, so this is manageable.
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).
