This muxer solely exists to test the fifo muxer via a dedicated
test tool in libavformat/tests/fifo_muxer.c. It fulfills no
other role and it is only designed with this role in mind.
The latter can be seen in two facts: The muxer uses printf
for logging and it simply presumes the packets' data to contain
a FailingMuxerPacketData (a struct duplicated in fifo_test.c
and tests/fifo_muxer.c.); in particular, it presumes packets
to have data at all, but this need not be true with side-data
only packets and a segfault can easily be triggered by e.g.
encoding flac (our native encoder sends a side-data only packet
with updated extradata at the end of encoding).
This patch fixes this by moving the test muxer into the fifo
test tool, making it inaccessible via the API (and actually
removing it from libavformat.so and libavformat.a).
While this muxer was accessible via e.g. av_guess_format(),
it was not really usable for an API user as FailingMuxerPacketData
was not public. Therefore this is not considered a breaking change.
In order to continue to use the test muxer in the test tool,
the ordinary fifo muxer had to be overridden: fifo_muxer.c
includes lavf/fifo.c but with FIFO_TEST defined which makes
it support the fifo_test muxer. This is possible because
test tools are always linked statically to their respective
library.

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.

The formal title of the muxer according to the specification
is "RCWT (Raw Captions With Time)", so canonize this
in the long name of the codec and docs.
In the documentation section, point #2 was wrong: ccextractor
extracts the Closed Captions data and stores normalized bits
similarly to this muxer.

For unknown geokey values, get_geokey_val() returns
"Unknown-%d" with val being used for %d. This string
is allocated and therefore all the known geokey values
(static strings) are strdup'ed. In case this fails
it is either ignored or treated as "Unknown-%d".
(Furthermore it is possible to call av_strdup(NULL),
although this is not documented to be legal.)
This commit changes this by only returning the static strings
in get_geokey_val(); the unknown handling and strdup'ing
is moved out of it.

Apparently it can happen that avfilter_graph_request_oldest() returns
EAGAIN, yet av_buffersrc_get_nb_failed_requests() returns 0 for every
input.
Works around #10795, though the root issue is most likely in the
scale2ref filter.
This is thankfully passed through verbatim by libdav1d, so we can parse
it in our own code.
In theory, taking the DV profile from the packet-level configuration
struct is redundant since there is currently only one possible DV level
for AV1 (and all others would fail parsing), but this marginally
future-proofs it against possible new AV1-specific profiles being added
in the future.
At present, consume_update evaluates timeline state on all links for
a multi-input filter. This can lead to the filter being incorrectly
en/dis-abled when evaluation on a frame on a secondary link leads to
a different result than the frame on the current main link next in
line for processing.
This currently builds files in the libavcodec/x86/{vvc,h26x}
subdirectories, which is somewhat unexpected when building for
another architecture than x86.
The regular arch subdirectories are handled with
-include $(SRC_PATH)/$(1)/$(ARCH)/Makefile
in the toplevel Makefile. Switch this to a similar optional
inclusion, using $(ARCH).
