This replaces the myriad of existing lists in AVCodec by a unified API
call, allowing us to (ultimately) trim down the sizeof(AVCodec) quite
substantially, while also making this more trivially extensible.
In addition to the already covered lists, add two new entries for color
space and color range, mirroring the newly added negotiable fields in
libavfilter.
Once the deprecation period passes for the existing public fields, the
rough plan is to move the commonly used fields (such as
pix_fmt/sample_fmt) into FFCodec, possibly as a union of audio and video
configuration types, and then implement the rarely used fields with
custom callbacks.
The code is imported from libjpeg-turbo-3.0.1. The neon registers used
have been changed to avoid modifying v8-v15.

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.

Instead, use forward declarations; and in order not to affect
any user include these headers for them, but not internally.
This has the advantage of removing implicit inclusions of these
headers from almost all files providing codecs.

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.
This commit is the AVHWAccel analogue of commit
20f9727018: It moves the private fields
of AVHWAccel to a new struct FFHWAccel extending AVHWAccel
in an internal header (namely hwaccel_internal.h).

This would only be necessary if this header declared a function
that takes a (pointer to) struct AVCodecContext as parameter.

This decoding flag makes decoders drop all frames after a parameter
change, but what exactly constitutes a parameter change is not well
defined and will typically depend on the exact use case.
This functionality then does not belong in libavcodec, but rather in
user code
Added prerequisites that must be met before providing support for the MPEG-5 EVC codec
- Added new entry to codec IDs list
- Added new entry to the codec descriptor list
- Bumped libavcodec minor version
- Added profiles for EVC codec

For encoding, this field is entirely redundant with
AVCodecContext.framerate.
For decoding, this field is entirely redundant with
AV_CODEC_PROP_FIELDS.
Described in HEVC spec A.3.7. Bump minor version and add APIchanges
entry for new added profile.

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.
