Add an AVOption to the libjxl encoder wrapper, which exposes the flag
uses_original_profile in libjxl. For highly unusual ICC profiles where
the target needs to stay in the original space, this can be useful.

This BSF is supposed to be used in conjunction with mp3_header_compress,
which has been removed more than ten years ago in commit
c6080d8900. It mangled the headers
by removing the CRC field as well as fields that are supposed
to stay constant for the entirety of a stream (which are put into
extradata). This made these files unplayable; they need to be
decompressed with the BSF first (which does not happen automatically).
Even in this case the CRC does not get restored.
I am not aware that such compressed files exist at all; therefore
this commit removes the BSF completely.

It used to be used with preallocated packet buffers with
the old encode API, but said API is no more and therefore
there is no reason for this to be public any more.
So deprecate it and use an internal replacement
for the encoders using it as an upper bound for the
size of their headers.

This should hopefully clarify that the option only affects MSZ
full-width characters, and not all full-width ASCII. Additionally,
this matches the prefix with the upstream option.
Signed-off-by: TADANO Tokumei <aimingoff@pc.nifty.jp>
This patch adds two MSZ (Middle Size; half width) character
related options, mapping against newly added upstream
functionality:
* `replace_msz_japanese`, which was introduced in version 1.0.1
of libaribcaption.
* `replace_msz_glyph`, which was introduced in version 1.1.0
of libaribcaption.
The latter option improves bitmap type rendering if specified
fonts contain half-width glyphs (e.g., BIZ UDGothic), even
if both ASCII and Japanese MSZ replacement options are set
to false.
As these options require newer versions of libaribcaption, the
configure requirement has been bumped accordingly.

This will simplify the propagation of side data to decoders and from encoders.
Global side data will now reside in the AVCodecContext, thus be available
during init(), removing the need to propagate it inside packets.
Global and frame specific side data will therefore be distinct.

These defines are also used in other contexts than just AVCodecContext
ones, e.g. in libavformat. Furthermore, given that these defines are
public, the AV-prefix is the right one, so deprecate (and not just move)
the FF-macros.

This reverts commit eb88ccb92e.
AVCodecContext fields are the proper place for a decoder to export such values.
This change is in preparation for the following commits.
I've been sitting on this for 3 1/2 years now(!), and I finally got
around to fixing the loose ends and convincing myself that it was
correct. It follows the same basic structure as yadif_cuda, including
leaving out the edge handling, to avoid expensive branching.
Migrate the libjxl decoder wrapper from the decode_frame method to the
receive_frame method, which allows sending more than one frame from a
single packet. This allows the libjxl decoder to decode JPEG XL files
that are animated, and emit every frame of the animation. Now, clients
that feed the libjxl decoder with an animated JPEG XL file will be able
to receieve the full animation.

As this is an AV_CODEC_CAP_OTHER_THREADS decoder, threading is handled by the
underlying library. In this case, the frame delay is calculated by libdav1d
based on the values from avctx->thread_count and the private max_frame_delay
option.
Export said delay reported by the library in AVCodecContext.delay
