AVCodecParser has several fields which are not really meant
to be accessed by users, but it has no public-private
demarkation line, so these fields are technically public
and can therefore not simply be made private like
20f9727018 did for AVCodec.*
This commit therefore deprecates these fields and
schedules them to become private. All parsers have already
been switched to FFCodecParser, which (for now) is a union
of AVCodecParser and an unnamed clone of AVCodecParser
(new fields can be added at the end of this clone).
*: This is also the reason why split has never been removed despite
not being set for several years now.

Simple parser that only parses frame information.
This helps avoid requiring the software decoder on init to decode a
single frame, since the decoder can be quite slow.
Add a full parser to libavcodec for AV_CODEC_ID_JPEGXL. It finds the
end of the stream in order to packetize the codec, and it looks at
the headers to set preliminary information like dimensions and pixel
format.
Note that much of this code is duplicated from avformat/jpegxl_probe.c,
but that code will be removed and call this instead in the next commit.

The whole old next API has been deprecated in commit
7e8eba2d87, yet deprecating the next
pointer has been forgotten (the next pointers of other structures are
below the public API delimiter, but such a delimiter doesn't exist for
AVCodecParser).

I have attempted to write a JPEG2000 Parser. Have tested
by generating a file containing 14 frames, as mentioned
by Micheal. Have also tried testing with various packet
sizes by setting -frame_size option. Additionally,
fixed a few formatting issues as pointed out by Micheal.

Simple parser to set keyframes, frame type, structure, width, height, and pixel
format, plus stream profile and level.

And add it to the CONFIGURABLE_COMPONENTS list in Makefile. This way, changes
to the new file will be tracked and the usual warning to suggest re-running
configure will be shown.
