Fixes the build. It's a requirement when utilizing PIE.

If a sequence of JXL images is encapsulated in a container that has PTS
information, we should use the PTS information from the container. At
this time there is no container that does this, but if JPEG XL support
is ever added to NUT, AVTransport, or some other container, this commit
should allow the PTS information those containers provide to work as
expected.

These pixel formats have always been supported by libjxl, but at the
time this plugin was written, they were not in FFmpeg yet. Now that
they are in FFmpeg, we should support them.

FFmpeg doesn't support tv-range RGB throughout most of its pipeline, so
we should keep the warning. However, in case something does support it
we should at least keep it tagged properly. Additionally, the encoder
writes this tag if the space is tagged as such so this makes a round
trip work as it should.
Also, PNG doesn't support nonzero matrices but we only warn and ignore
in that case, so we have no reason to error out for illegal cICP ranges
either (i.e. greater than 1).

For memcpy and memcmp, we need to multiply by the element size,
otherwise we're copying and comparing only a fraction of the buffer.
For decorrelate_sr, the buffer p1 is the one that is mutated;
copy and check p1 instead of p2.
For decorrelate_sm, both buffers are mutated, so copy and check
both of them.
For decorrelate_sm, the memcpy initialization of p1 and p1_2 was
reversed - p1 is filled with randomize, but then memcpy copies from
p1_2 to p1. As p1_2 is uninitialized at this point, clang concluded
that the copy was bogus and omitted it entirely, triggering failures
in this test on x86 (where there was an existing assembly implementation
to test).

* filter subtitle/data options out of main, video and audio sections
* add filters that were missing entirely from the subtitle section
* add a missing section for advanced subtitle options
So they don't clutter the standard help output.
-loglevel is marked because there is no need to show two options (-v and
-loglevel) that do the same thing.
Currently it requires every single OPT_SPEC option to be accompanied by
an array of alternate names for this option. The vast majority of
options have no alternate names, resulting in a large numbers of
unnecessary single-element arrays that merely contain the option name.
Extend the option parsing API to allow marking options as having
alternate names, or as being the canonical name for some existing
alternatives. Use this new information to avoid the need for
abovementioned unnecessary single-element arrays.
This option flag only carries nontrivial information for options that
call a function, in all other cases its presence can be inferred from
the option type (bool options do not have arguments, all other types do)
and is thus nothing but useless clutter.
Change the option parsing code to infer its value when it can, and drop
the flag from options where it's not needed.
It causes those options to be parsed as either
* -autofoo 0/1 (with an argument)
* -noautofoo (without an argument)
This is unnecessary, confusing, and against the documentation; these are
also the only two bool options that take an argument.
This should not affect the users, as these options are on by default,
and are supposed to be used as -nofoo per the documentation.
Otherwise an unitialized stack value would be copied to FPSConvContext.
As it's then never used, it tends not to be a problem in practice,
however it is UB and some compilers warn about it.
The check for UWP mode was duplicated from right above, in
d54127c41a.
Also, instead of several lines with "enabled uwp && ...", make one
"if enabled uwp; then" block.

The current pack_output function pointer is a property of the decoder,
rather than a constant method provided by the DSP code. Indeed, except
for an unused initialisation, the field is never used in DSP code.
The penultimate loop iteration could pick any vl such that:
vlenb/4 < vl <= vlenb/2
Thus if the total length is not a multiple of vlenb/2, the vfadd.vf
on the penultimate iteration would yield corrupt values for the last
iteration.
To avoid this, force vl = vlen/2 until the last iteration. Unfortunately
this latent bug is not reproducible with either hardware or QEMU as of now.
This skips the round-trip to scalar register for the sliding 'x'
coefficients, improving performance by about 5%. The trick here is that
the vector slide-up instruction preserves elements in destination vector
until the slide offset.
The switch from vfslide1up.vf to vslideup.vi also allows the elimination
of data dependencies on consecutive slides. Since the specifications
recommend sticking to power of two offsets, we could slide as follows:
vslideup.vi v8, v0, 2
vslideup.vi v4, v0, 1
vslideup.vi v12, v8, 1
vslideup.vi v16, v8, 2
However in the device under test, this seems to make performance slightly
worse, so this is left for (in)validation with future better hardware.
