This codec supports FLAG_B_PICTURE_REFERENCES. We need to correctly fill
the reference_pic_flag with is_reference variable instead of 0 for B
frames.

libva2 doesn't require a fixed surface-array any more, so we may use
dynamic frame pool for decoding when libva2 is available, which allows a
downstream element stores more frames from VAAPI decoders and fixes the
error below:
$ ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi \
-i input.mp4 -c:v hevc_vaapi -f null -

This diff removes 4 unused ARMv7 NEON fixed-point DSP functions.
The function were originally moved here by 4958f35a2 (Dec 2013).
After 9e05421db (Jan 2021), as part of the refactor of the AC3
DSP to consistently use 32-bit sample format in the encoder, these
functions were removed from the DSP function table, but the ARMv7
implementations were kept.

Fixes a regression due to the fact that the colorspace filter does
not use the new API introduced by 8c7934f73a.
The scale filter uses it since 45e09a3041, and the setparams
filter since 3bf80df3cc.
Example:
ffprobe -f lavfi yuvtestsrc,setparams=color_primaries=bt470bg:color_trc=
bt470bg:colorspace=bt470bg,colorspace=bt709:range=tv,scale,showinfo
Before:
color_range:unknown color_space:bt470bg ...
After:
color_range:tv color_space:bt709 ...

When starting on a SEI recovery point close enough to the end of
the stream that draining starts before the recovery point's frame
is output, there can be non-recovered frames in the delayed picture
buffer that would currently cause the decoder to fail to output a
frame. This commit skips such frames and outputs the first recovered
frame, if there exists one.

When decoding starts at a SEI recovery point very shortly before the
end of the video stream, there can be frames which are decoded before
the recovery point's frame is output and which will only be output once
the draining has started. Previously, these frames would never be set
as recovered. This commit copies the logic from h264_select_output_frame
to send_next_delayed_frame to properly mark such frames as recovered.
Fixes ticket #10936.

sps_log2_ctu_size_minus5 is between 0 and 2, with 3 reserved for future
use. The VVC decoder allows sps_log2_ctu_size_minus5 to be 3, and so
ctb_size_y should be at least 16 bits to prevent overflows. An
alternative patch would leave sps_log2_ctu_size_minus5 as 8 bits and
disallow sps_log2_ctu_size_minus5 = 3.

The first release of the CTS for AV1 decoding had incorrect
offsets for the OrderHints values.
The CTS will be fixed, and eventually, the drivers will be
updated to the proper spec-conforming behaviour, but we still
need to add a workaround as this will take months.
Only NVIDIA use these values at all, so limit the workaround
to only NVIDIA. Also, other vendors don't tend to provide accurate
CTS information.
This is needed by Vulkan. Constructing this can't be delegated to CBS
because packets might contain multiple frames (when non-shown frames are
present) but we need separate snapshots immediately before each frame
for the decoder.
reserve_index_space is a size, not an index.
Also refer to the variable in the description.

When Split frame encoding is enabled, each input frame is partitioned into
horizontal strips which are encoded independently and simultaneously by
separate NVENCs, usually resulting in increased encoding speed compared to
single NVENC encoding.

As we can read in ST 2086:
Values outside the specified ranges of luminance and chromaticity values
are not reserved by SMPTE, and can be used for purposes outside the
scope of this standard.
This is further acknowledged by ITU-T H.264 and ITU-T H.265. Which says
that values out of range are unknown or unspecified or specified by
other means not specified in this Specification.

We have test to make sure that certain configurations do print
warnings. However, the normal operation of the muxer within this
test always printed a warning, so those tests to check for
extra warnings didn't essentially guard anything.
The warning that always was printed, "track 1: codec frame size is
not set" was not present in the libav fork where this testcase
originated, it was removed in f234e8a32e.
Set the frame size for the audio stream to silence the warning,
and use this frame size in a couple later calculations, and check
that one test configuration doesn't print warnings.
Setting the frame size apparently changes the rounding of a timestamp
in the ismv muxing testcase.

The strings here are so short that using a pointer is wasteful
(the longest string takes nine bytes; on 64 bit systems,
the pointer+padding already take 12 bytes). So avoid them
and add asserts to ensure that no one ever tries to use a too
long tag.

These memcpy operands only depend upon sizeof(SampleType)
(and this size is actually the same for both the fixed-point
and the floating-point encoders for most (all supported?)
