d5040b5560 avcodec/itut35: rename some provider codes
In general, a provider code corresponds to a company/organization, and
the name should be that of the company, not of a given feature.
The feature is signalled in the "provider oriented code".

The exception is HDR Vivid, where the code 0x0004 indicates the HDR Vivid
feature itself rather than CUVA (China UHD Video Industry Alliance),
according to the UHD World Associations 'HDR Video Technology Part 2-1
Application Guide to System Integration' document.

ITU_T_T35_PROVIDER_CODE_CUVA -> ITU_T_T35_PROVIDER_CODE_HDR_VIVID
ITU_T_T35_PROVIDER_CODE_LCEVC-> ITU_T_T35_PROVIDER_CODE_VNOVA

a3ec70b2cf avcodec/itut35: always check the provider code and country code together
ITU-T T.35 provider codes are attributed by national bodies and it's
possible to have collisions across countries. This is why the country code
must always be checked as well.

Use if statements rather than nested switches which would be unreadable.

f9c5c5358c avcodec/videotoolbox: add AV1 hardware acceleration
Use AV1DecContext's current_obu to access the original OBUs, and
feed them to videotoolbox, rather than the bare slice data passed
via decode_slice.

This requires a small addition to AV1DecContext, for keeping track

9fb3d640fb avcodec/av1dec: Always set ret before goto end
Before 0f8763fbea, av1_frame_ref()
and update_reference_list() could fail and therefore needed to
be checked, which incidentally set ret. This is no longer happening,
leading to a potential use of an uninitialized value which is
also the subject of Coverity ticket #1596605.

Fix this by always setting ret before goto end; do not return
some random ancient value.

d0392619a7 avcodec/dovi_rpu: store entire config record
And make it public.

For encoding, users may also be interested in the configured level and
compatibility ID. So generalize the dv_profile field and just expose the
whole configuration record.

This makes the already rather reductive ff_dovi_update_cfg() function
almost wholly redundant, since users can just directly assign
DOVIContext.cfg.

0f8763fbea avcodec/av1dec: Use ProgressFrames
AV1 can put a frame into multiple reference slots;
up until now, this involved creating a new reference
to the underlying AVFrame; therefore av1_frame_ref()
could fail.
This commit changes this by using the ProgressFrame API
to share the underlying AVFrames.

(Hint: vaapi_av1_surface_id() checked whether the AV1Frames
contained in the AV1DecContext were NULL or not (of course
they were not); this has been changed to actually check for
whether said AV1Frame is blank or not.)

It is unnecessary since the removal of non-thread-safe callbacks

AVCodecContext has only been used as logcontext.

Removing ff_thread_release_buffer() allowed to remove AVCodecContext*
parameters from several other functions (not only unref functions,
but also e.g. ff_h264_ref_picture() which calls ff_h264_unref_picture()
on error).

3e9b8d14e5 avcodec/cbs: Use RefStruct-API for unit content
This avoids allocations and error checks etc. as well
as duplicate pointer lists in the CodedBitstreamFooContexts.
It also avoids casting const away for use as opaque,
as the RefStruct API supports const opaques.

The fact that some of the units are not refcounted
(i.e. they are sometimes part of an encoding context
like VAAPIEncodeH264Context) meant that CodedBitstreamUnit
still contains two pointers, one to the content
and another ownership pointer, replacing the AVBufferRef* pointer.
