The current pbc might be small for an obu frame, so a new pbc is
required then parse this obu frame again. Because
CodedBitstreamAV1Context has already been updated for this obu frame, we
need to restore CodedBitstreamAV1Context, otherwise
CodedBitstreamAV1Context doesn't match

In some videos, SPS will be stored before VPS in hvcC box,
parse SPS does not depend on VPS, so the video is expected to be processed
normally.
Added "parsed_vps" parameter to indicate whether VPS have been parsed.
Only VPS have been parsed can be verified during SPS parsing.

The DCBZL instruction is not available for the e500v1 and e500v2
architectures, but may still be recognized by the toolchain, so we need to
remove the test for it explicitly for these architectures.

Users can't make anything with its content.
Making it opaque might allow us to avoid one level of indirection.

Anton really dislikes the av_fast_* naming and instead wants this to be
called av_realloc_array_reuse(). I don't care either way. Any more
opinions

Hi,
This should address all comments from the previous version.
Changes since version 5:
- No longer nest CPU glag checks.
- Remove all forced flags stuff (redundant after previous point).
- Rename CPU flags to make them more legible.
- Simplify/optimise AAC PS stereo interleave using 2-s
From: Rémi Denis-Courmont
This introduces compile-time and run-time CPU detection on RISC-V. In
practice, I doubt that FFmpeg will ever see a RISC-V CPU without all of
I, F and D extensions, and if it does, it probably won't have run-time
detection. So the flags are essentially always set.
But a

When force_original_aspect_ratio and force_divisible_by are both
used, dimensions are now rounded to the nearest allowed multiple of
force_divisible_by rather than first rounding to the nearest integer and
then rounding in a static direction. This results in less distortion of
the aspect ratio.

ff_check_pixfmt_descriptors() was added in commit

the values of enum AVPixelFormat were not contiguous;
instead there was a jump from 111 to 291 (or from 115
to 295 depending upon AV_PIX_FMT_ABI_GIT_MASTER).

Instead use av_pix_fmt_desc_next(). It is still possible
to check its return values by comparing it with the
(currently) expected values and the code does so.

Fixes the j2k-dwt FATE-test; also fixes #9945.
(I don't know whether the multiplication can overflow.)
