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.

(cherry picked from commit a824c6f2f6)
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.

Handling AVPacketSideData directly, which can used on structs other than
AVPacket.
This will be useful in the following commits.

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

Some specifications require the size of ld/eld frames to be 480 samples
instead of the default 512. libfdk_aac provides an option to set an alternative
frame size, but it's not exposed via the ffmpeg interface.
This patch adds a frame_length option to solve this problem.

Frame counters can overflow relatively easily (INT_MAX number of frames is
slightly more than 1 year for 60 fps content), so make sure we use 64 bit
values for them.
Also deprecate the old 32 bit frame_number attribute.

This is intended to be a more convenient replacement for
reordered_opaque.
Add support for it in the two encoders that offer
AV_CODEC_CAP_ENCODER_REORDERED_OPAQUE: libx264 and libx265. Other
encoders will be supported in future commits.
