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).

GIF palette entries are not compressed, and writing 256 entries,
which can be up to every frame, uses a significant amount of
space, especially in extreme cases, where palettes can be very
small.
Example, first six seconds of Tears of Steel, palette generated
with libimagequant, 320x240 resolution, and with transparency
optimization + per frame palette:
* Before patch: 186765 bytes
* After patch: 77895 bytes

This option will disable the writing of the global palette in global
GIF header if it is set to 0, causing only the frame-level palette
to ever be written.
This will be useful later on when further frame-level palette
optimizations are introduced.
The default is 1, which maintains current default behavior.

AVID streams - currently handled by the AVRN decoder - can be (depending
on extradata contents) either MJPEG or raw video. To decode the MJPEG
variant, the AVRN decoder currently instantiates a MJPEG decoder
internally and forwards decoded frames to the caller (possibly after
cropping them).
This is suboptimal, because the AVRN decoder does not forward all the
features of the internal MJPEG decoder, such as direct rendering.
Handling such forwarding in a full and generic manner would be quite
hard, so it is simpler to just handle those streams in the MJPEG decoder
directly.
The AVRN decoder, which now handles only the raw streams, can now be
marked as supporting direct rendering.
This also removes the last remaining internal use of the obsolete
decoding API.

Current code is very confused and confusing. It uses two different
reference frames - "previous" and "last" - when only one is really
necessary. It also confuses the two, leading to incorrect output with
APNG_DISPOSE_OP_PREVIOUS mode.
Fixes#9017.
FF_CODEC_CAP_ALLOCATE_PROGRESS makes no sense because the decoder does
not support frame threading.
FF_CODEC_CAP_SKIP_FRAME_FILL_PARAM makes no sense because the decoder
does not handle skip_frame.
No buffer will be fetched from the pool after it's uninitialized, so there's
no benefit from waiting until every single buffer has been returned to it
before freeing them all.
This should free some memory in certain scenarios, which can be beneficial in
low memory systems.
Based on a patch by Jonas Karlman.

Clang infers from the existence of a default case that said case can be
taken. In case of libavcodec/bitstream.c said default case consisted of
an av_assert1 that evaluates to nothing in case of the ordinary assert
level. In this case (that doesn't happen) a variable wouldn't be
initialized, so Clang emitted Wsometimes-uninitialized warnings.
Solve this by making sure that the default path also initializes
the aforementioned variable.
