In practice, we encounter streams that have one or more temporal units
error. When that kind of error temporal units is in annex b format, the
whole temporal unit should be discarded.
But the temporal units before it are correct and can be used. More
important, because of the error temporal unit, the parser is in a wrong
state and all later temporal unit are also parsed uncorrectly.
We need to add this API to reset the annex_b state only when we meet
some temporal unit error.

1. store more tile info when parse tile group.
The column, row, tile offset and tile data size are all useful for
decoder process, especially for HW kind decoder such as VAAPI dec.
Also fix the tile group skip size for each tile data.
2. No min_inner_tile_width requirement in newest spec.
3. Calculate the sbs of each tile for both uniform tile and non-uniformi
tile.

The metadata OBUs, for example, ITUT_T35 has an undefined payload such
as itu_t_t35_payload_bytes field in AV1 spec, which may cause the failure
of parsing the trailings bits. We can give a warning and ignore this kind
of errors.

In case that "pic_order_cnt_type" is equal to zero, ref picture
list for B slice should not include non-existing picture
as per spec 8.2.4.2.3. And, the second field is not needed
for the process of frame picture reference list construction
since it needs to be frame unit, not field picture in that case.

We were trying to construct reference picture list even for
I slice before this commit. Reference list is required only for
P, SP and B slices. Also, if all existing reference pictures
are gap pictures, we don't need to construct lists.

force_videometa should mean that the buffer must use video meta to
map correctly. When the stride or the offset of the alloc_info is
different from the src caps, the downstream must use video meta.
So this flag should not link with the RAW caps only. All kinds of
caps(memory:VAMemory, memory:DMABuf) should have this flag.
Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/1711>
When the downstream element reports an ANY caps, and it also fails to
support VideoMeta, we should fallback to the system memory.
Note: the basetransform kind elements never return valid allocation
query before set_caps(). So, if a basetransform return an ANY sink
caps, we always fallback to system memory for it.

Allocate a GArray which is used to fill
VAPictureParameterBufferH264.ReferenceFrames (called per frame),
instead of alloc/free per frame.
Also this commit is to fix the condition where long-term reference
picture is needed for VAPictureParameterBufferH264.ReferenceFrames
entry.

We don't need to preserve input color range for transformed target
color space. Also some GPUs doesn't seem to be happy with 16-235
color range for RGB color space.
Also, since our default display target color space is
DXGI_COLOR_SPACE_RGB_FULL_G22_NONE_P709, choosing full color range
would make more sense.

When gst_va_dmabuf_allocator_setup_buffer_full() receives info (not NULL) it is
supposed that this buffer is not part of the allocator pool, so it has to be
de-allocated as soon it is freed.
This patch sets the destroy notify of the assigned GstVaBufferSurface if info is
not NULL.

Initial support for interlaced stream. Subclass should implement
new_field_picture() vfunc. Otherwise, baseclass will assume that
subclass doesn't support interlaced stream.
Restrictions:
* Reference picture modification process for interlaced stream
is not implemented yet
* PAFF (Picture Adaptive Frame Field) is not properly implemented.
* Field display ordering (e.g., top-field-first) decision should
be enhanced via picture timing SEI parsing
* Gap in field picture should be handled

Managing reference picture type by using two variables
(ref and long_term) seems to be redundant and that can be
represented by using a single enum value.
This is to sync this implementation with gstreamer-vaapi so that
make comparison between this and gstreamer-vaapi easier and also
in order to minimize the change required for subclass to be able
to support interlaced.
