Add new gst_vaapi_surface_proxy_new() helper to wrap a surface into
a proxy. The main use case for that is to convey additional information
at the proxy level that would not be suitable to the plain surface.
Fix gst_vaapi_surface_proxy_copy() to copy the view-id element, thus
fixing random frames skipped when vaapipostproc element is used in
passthrough mode. In that mode, GstMemory is copied, thus including
the underlying GstVaapiVideoMeta and associated GstVaapiSurfaceProxy.
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".
When decoding failed, or that the frame was dropped, the associated
surface proxy is not guaranteed to be present. Thus, the GST_DEBUG()
message needs to check whether the proxy is actually present or not.

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.
The user-defined destroy notify function is meant to be called only when
the surface proxy was fully released, i.e. once it actually released the
VA surface back to the underlying pool.
Fix GstVaapiPicture, GstVaapiSlice and GstVaapiSurfaceProxy initialization
sequences to have the expected default values set beforehand in case of an
error raising up further during creation. i.e. make it possible to cleanly
destroy those partially initialized objects.

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 helper macros to retrieve the VA surface information like size
(width, height) or chroma type. This is a micro-optimization to avoid
useless function calls and NULL pointer re-checks in internal routines.
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.
Make GstVaapiID a gsize instead of guessing an underlying integer large
enough to hold all bits of a pointer. Also drop GST_VAAPI_ID_NONE since
this is plain zero and that it is no longer passed as varargs.
Port GstVaapiVideoPool, GstVaapiSurfacePool and GstVaapiImagePool to
GstVaapiMiniObject. Drop gst_vaapi_video_pool_get_caps() since it was
no longer used for a long time. Make object allocators static, i.e.
local to the shared library.
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.
Make GstVaapiSurfaceProxy only a thin wrapper around a VA context and a
VA surface. i.e. drop any other attribute like timestamp, duration,
interlaced or top-field-first.
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.
This is a preferred thread-safe version. Also add an inline version of
g_clear_object() if compiling with glib < 2.28.

Add new "interlaced" attribute to GstVaapiSurfaceProxy. Use this in
vaapipostproc so that to handles cases where bitstream is interlaced
but almost only frame pictures are generated. In this case, we should
not be alternating between top/bottom fields.
