Regression since fd172185580c1ccdcfb90bbfdb59fa806fad3117;
triggered by vp4/KTkvw8dg1J8.avi in the FATE suite, but not
when running fate as this code is not used when the bitexact
flag is set.

Because of ffio_ensure_seekback() a seek error normally should only happen if
the end of file is reached during checking for the junk run-in. Also use proper
error code.
Signed-off-by: Marton Balint <cus@passwd.hu>
(cherry picked from commit 49e018d6fe)
We are protecting the checked buffer with ffio_ensure_seekback(), so if the
inner check fails with a seek error, that likely means the end of file was
reached when checking for the next frame. This could also be the result of a
wrongly guessed (larger than normal) frame size, so let's continue the loop
instead of breaking out early. It will end sooner or later anyway.

(cherry picked from commit b75e604fe5)
Otherwise the subsequent ffio_ensure_seekback calls destroy the buffer of the
earlier. The worst case ~66kB seekback is so small it is easier to request it
entirely.

0d17f5228f.

(cherry picked from commit 5a06d3810e)
Invalid input files may contain film grain metadata which survives
ff_h274_film_grain_params_supported() but does not pass
av_film_grain_params_select(), leading to a SIGSEGV on hevc_frame_end().
Fix this by duplicating the av_film_grain_params_select() check at frame
init time.
An alternative solution here would be to defer the incompatibility check
to hevc_frame_end(), but this has the downside of allocating a film
grain buffer even when we already know we can't apply film grain.

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.

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.

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().
