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.

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.

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.

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.

As per spec 7.4.3 Slice header semantics, the flag value is derived as
MbaffFrameFlag = (mb_adaptive_frame_field_flag && !field_pic_flag)
and DXVA uses the value.
Regarding FrameNumList, in case of long-term ref, FrameNumList[i]
value should be long_term_frame_idx not long_term_pic_num.

This add HEVC decoding support into the new VA plugin. This implementation has
been tested using the ITU comformance test (through fluster). It fails all
MAIN10 tests, as this is not implemented yet along with the following:
CONFWIN_A_Sony_1 (looks fine, but md5sum is incorrect)
PICSIZE_A_Bossen_1 (height too high)
PICSIZE_B_Bossen_1 (same)
VPSSPSPPS_A_MainConcept_1 (parser issue)

This causes no changes to the profile but keeps the existing settings.
The profile can also be changed from e.g. the card's configuration
application and in that case probably should be left alone.
The default is the new value as it keeps the profile setting as it is,
which is consistent with the previous behaviour in 1.18.

In our va implemenation, we just use image's info to map the buffer.
The padding info just plays a role as a place holder to expand the
allocation size in caps when decoding size is bigger than display
size. So the padding_right or padding_left does not change the result.
But we find if using padding_left, it is hard to meet the requirement
of gst_video_meta_validate_alignment(), when the video meta's stride
is different from the allocation width.

We have already done the jobs in gst_va_base_dec_decide_allocation()
and no need to call base class' decide_allocation() again. The base
class' decide_allocation() will set_format() again and let use do the
image/surface testing again, which is low performance and no needed.

Use this standalone function to update the allocator info and make
all ensure_image() and mem_alloc() API clean.
We also change the default way of using image. We now set the non
derive manner as the default manner, and if it fails, then fallback
to the derived image manner.
On a lot of platforms, the derived image does not have caches, so the
read and write operations have very low performance.
