Instal <gst/vaapi/gstvaapiutils_h264.h> header but only expose the
H.264 levels in there. The additional helper functions are meant
to be private for now.
Fixes a crash when multiple vaapidecode elements are finalized since
the debug category is created once in the class init method.
This is a regression from git commit 7e58d60.

Fix formts for various GST_DEBUG et al. invocations. More precisely,
make size_t arguments use the %zu format specifier accordingly; force
XID formats to be a 32-bit unsigned integer; and fix the format used
for gst_vaapi_create_surface_with_format() error cases since we have
been using strings nowadays.
The following helper functions are no longer used, thus are removed:
- gst_vaapi_video_format_from_structure()
- gst_vaapi_video_format_from_caps()
- gst_vaapi_video_format_to_caps()
Use standard GstVideoInfo related functions to build the output caps,
thus directly preserving additional fields as needed, instead of
manually copying them over through gst_vaapi_append_surface_caps().
Also ensure that the input caps are fixated first.
Add new helper functions to build video template caps.
- gst_vaapi_video_format_new_template_caps():
create GstCaps with size, frame rate and PAR to full range
- gst_vaapi_video_format_new_template_caps_from_list():
try to create a "simplified" list from the supplied formats
Add new helper functions to build GValues from GstVideoFormat:
- gst_vaapi_value_set_format():
build a GValue from the supplied video format
- gst_vaapi_value_set_format_list():
build a GValue list from the supplied array of video formats
Replace gst_vaapi_display_get_{decode,encode}_caps() APIs with more
more convenient APIs that return an array of GstVaapiProfile instead
of GstCaps: gst_vaapi_display_get_{decode,encode}_profiles().
Replace gst_vaapi_display_get_{image,subpicture}_caps() APIs, that
returned GstCaps, with more convenient APIs that return an array of
GstVideoFormat: gst_vaapi_display_get_{image,subpicture}_formats().
Makes the copies of a buffer reference their own GLTextureUploadMeta
user data and prevent the original buffer accessing already freed
memory if its copies has been released and freed.

Factor out propose_allocation() hooks, creation of video buffer pool
for the sink pad, conversion from raw YUV buffers to VA surface backed
buffers. Update vaapidecode, vaapiencode and vaapipostproc to cope
with the new GstVaapiPluginBase abilities.
Fix display creation code to check that any display obtained from a
neighbour actually has the type we expect. Note: if display type is
set to "any", we can then accept any VA display type.
Move common VA display creation code to GstVaapiPluginBase, with the
default display type remaining "any". Also add a "display-changed"
hook so that subclasses could perform additional tasks when/if the
VA display changed, due to a new display type request for instance.
All plug-ins are updated to cope with the new internal APIs.
Introduce a new GstVaapiPluginBase object that will contain all common
data structures and perform all common tasks. First step is to have a
single place to hold VA displays.
While we are at it, also make sure to store and subsequently release
the appropriate debug category for the subclasses.
The GLTextureUploadMeta implementation assumed that for each upload()
sequence, the supplied texture id is always the same as the one that
was previously cached into the underlying GstVaapiTexture. Cope with
any texture id change the expense to recreate the underlying VA/GLX
resources.

Requesting the GLTextureUpload meta on buffers in the bufferpool
prevents such metas from being de-allocated when buffers are released
in the sink.
This is particulary useful in terms of performance when using the
GLTextureUploadMeta API since the GstVaapiTexture associated with
the target texture is stored in the meta.

Make GstVideoGLTextureUploadMeta::upload() implementation more robust
when the GstVaapiTexture associated with the supplied texture id could
not be created.
Improve robustness when some expected packets where not received yet
or that were not correctly decoded. For example, don't try to decode
a picture if there was no valid frame headers parsed so far.

Conformance test Base_Ext_Main_profiles/BA3_SVA_C.264 complys with
extended profile specifications. However, the SPS header has the
constraint_set1_flag syntax element set to 1. This means that, if
a Main profile compliant decoder is available, then it should be
able to decode this stream.
This changes makes it possible to fall-back from Extended profile
to Main profile if constraint_set1_flag is set to 1.

Recognize streams marked as conforming to the "Constrained Baseline
Profile". If VA driver supports that as is, fine. Otherwise, fallback
to baseline, main or high profile.
Constrained Baseline Profile conveys coding tools that are common
to baseline profile and main profile.

The GStreamer codecparser layer now parses the scaling lists in zigzag
scan order, as expected, so that to match the original bitstream layout
and specification. However, further convert the scaling lists into
raster scan order to fit the existing practice in most VA drivers.

The previous fix was only valid to express the maximum size of the
macroblock layer, i.e. without any headers. Now, also account for
the slice headers and top picture header, but also any other header
we might stuff into the VA coded buffer, e.g. sequence headers.
Fix coded buffer size for each codec. A generic issue was that the
number of macroblocks was incorrectly computed. The second issue was
specific to MPEG-2 were the max number of bits per macroblock, and
as defined by the standard, was incorrectly mapped to the (lower)
H.264 requirement. i.e. 4608 bits vs. 3200 bits limit.
Change get_context_info() into a set_context_info() function that
initializes common defaults into the base class, thus allowing the
subclasses to specialize the context info further on.
The set_context_info() hook is also the location where additional
context specific data could be initialized. At this point, we are
guaranteed to have valid video resolution size and framerate. i.e.
gst_vaapi_encoder_set_format() was called beforehand.
