Key line from the spec is:
"All SPS NAL units with a particular value of sps_seq_parameter_set_id
in a CVS shall have the same content."
Prior to this patch, the VVC decoder's behaviour on encountering a
duplicated SPS ID (within the entire bitstream, not restricted to
a CVS) was simply to replace the entry in the SPS lookup table with the
new data. Illegal bitstreams with multiple SPSs in the same CVS sharing
an ID but differing elsewhere could cause all manner of issues.
The patch tracks which SPS IDs have been used in the given CVS using the
new sps_id_used field of VVCParamSets. If it encounters an SPS with an
ID already in use and whose content differs from the previous SPS, it
throws an AVERROR_INVALIDDATA.

ff_ass_subtitle_header_* still used explicit CRLF linebreaks
eventhough they will get normalised to LF later since commit
7bf1b9b357. Just directly use LF.
Unlike what the old comment suggested, standard ASS has no character
escape mechanism, but a closing curly bracket doesn't even need one.
For manual authored sub files using a full-width variant of an
appropriate font and with scaling and spacing modifiers is a common
workaround.
This is not an option here, but we can still make things much less bad.
Now the desired opening bracket still shows up in libass, and
standard renders will merely display a backslash in its place
instead of stripping the following text like before.
Backslashes cannot be escaped by a backslash in any ASS renderer,
but unless followed by specific characters it is just printed out.
Insert a word-joiner character after a backslash to break up
active sequences without changing the visual output.
v2.0.0 is already four years old and even newer versions are available on
stable distro releases.
With this we stop setting codec capabilities during static data initialization.

Creating vsynth_lena.yuv needs the FATE suite,
yet several tests in ffmpeg.mak without a dependency
on samples used it as input file. Fix this by using
vsynth1.yuv (which does not have such a dependency)
instead.
Also use vsynth1.yuv in fate-shortest to avoid
the samples dependency in this test, too.
Fixes ticket #10947.

This is possible by not converting from LSBF to MSBF; instead
add LSBF LUTs.
This approach necessitates reversing the initial values.

ff_dsd2pcm_translate() works internally by converting LSBF input
to MSBF upon reading; its buffer is therefore always MSBF
and should therefore be initialized with MSBF silence;
but this is not true since e3d8963c3c
which this patch effectively reverts.

av_realloc_f() frees the buffer it is given on allocation
failure. But in this case, the buffer is an array of
ownership pointers, causing leaks on error. Furthermore,
the count of pointers is unchanged on error and the codec's
close function uses it to free said ownership pointers,
causing a NPD.
This is a regression since 46412a8935.
Fix this by switching to av_realloc_array().

The alignment of all the parameters in diff_bytes can be
anything the despite the documentation claiming otherwise.
8ecd383122 was based around
said documentation and is therefore insufficient to fix
e.g. the misaligned loads that happen in the huffyuvbgra
and huffyuvbgr24 vsynth FATE-tests.

Newer specifications such as H.273 have, and probably will further
in the future add new values to these, so - instead of trying to update
these limits - we should simply check if the values are not set to the
value of "unspecified".
This should allow newer avutil values such as IPT-C2 or YCgCo-R
variants be passed to x265 itself, which apparently does its own
validation further down the line.
* SMPTE ST 2128 IPT-C2 defines the coefficients utilized in DoVi
Profile 5. Profile 5 can thus now be represented in VUI as
{AVCOL_RANGE_JPEG, AVCOL_PRI_BT2020, AVCOL_TRC_SMPTE2084,
AVCOL_SPC_IPT_C2, AVCHROMA_LOC_LEFT} (although other chroma
sample locations are allowed). AVCOL_TRC_SMPTE2084 should in
this case be interpreted as 'PQ with reshaping'.
* YCgCo-Re and YCgCo-Ro define the bitexact YCgCo-R, where the
number of bits added to a source RGB bit depth is 2 (i.e., even)
and 1 (i.e., odd), respectively.
GCC 9-13 do not emit warnings for this at all optimization
levels even when -Wmaybe-uninitialized is not disabled.
