Depending on the magnitude of the output values, the potential
errors can be larger.
This fixes errors in the lls tests on x86_32 for some seeds,
observed with GCC 11 (on Ubuntu 22.04, with the distro compiler,
with -m32).

This fixes an 11-year-old bug in the rgb2xyz functions, when used with a
negative stride. The current loop bounds turned it into a no-op.
Additionally, this increases performance on highly cropped images, whose
stride may be substantially higher than the effective width.

This code uses no encoder properties or state besides its name, and is
mostly muxer logic, and thus belongs more properly into the muxer.
The results of several test change due to different metadata tag order
(the "encoder" tag is now set first).
The unaligned width test cases fail on i386; we have an assembly
function of rgb24toyv12 which is enabled only within
"#if ARCH_X86_32 && HAVE_7REGS", which seems to fail these new
test cases for unaligned widths.
As that assembly function has existed for a long time in that form,
the issue probably isn't very recent, thus skip testing these cases
for now.
Once the assembly function has been fixed, these test cases can
be readded.

Since c0666d8b, rgb24toyv12 is broken for width non-aligned to 16.
Add a simple wrapper to handle the non-aligned part.

The input file is MPEG range, so we should also encode to MPEG range
before comparing against it. This bug was avoided in the past because
YUVJ inputs were automatically converted back to limited range when converting
to a different pixfmt (in the absence of tagging). However, with proper YUV
negotiation in place, the default behavior is to preserve the YUV range
wherever possible. Since `rawvideo` does not signal or care about the YUV
range, we need to explicitly request the desired output range to force a
conversion.
Affects all rawvideo tests, in particular vsynth and owdenoise.
The test constructs 66 sine waves of different frequencies and joins
them into a 7th order ambisonic layout with extra non-diegetic
stereo. The channels are then shifted circularly with channelmap and
separated into individual streams for muxing with channelsplit.
Note that the last step is necessary because swr is not capable of
interleaving planar to packed for more than 64 channels, which would be
necessary to mux such a stream as PCM.
This reverts commit 110d8549d5.
I have been working through fixing bugs, particularly crashes I've
found using a fuzzer, in the VVC decoder for the past few months.
While I won't claim it is now bug-free, it is considerably more
resilient than it was and I think in a position to have the
experimental flag removed for release 7.1.
Additionally, most of the Main 10 features of VVC which were missing
version of the decoder released in 7.0 have now been implemented.
This includes the most major missing features: IBC, subpictures and RPR.

Fix "ost->st->avg_frame_rate = ost->frame_rate" in streamcopy_init()
being reset to input's frame rate a few lines below.
Note that in current code, there are some discrepancies amongst the
muxers. For example, avienc relies on time_base, so it is not affected
by this patch, whereas mxfenc and matroskaenc do use avg_frame_rate,
so this patch fixes -r being honored.
In the updated fate test, the input is (wrongly) probed as 50fps. With
this patch, the correct value (25fps) is successfully forced with -r.

The time_base was a bad guess.
Currently, fate-time_base test data assumed that overriding the input
time_base would affect the frame_rate, but this behaviour is not
documented, so just fix the fate data now that this is fixed.
Fix regression since 10185e2d4c:
previously, when streamcopying, the time_base was guessed from the
frame_rate considering it is often constant, so guessing the frame_rate
back from the time_base was often not a problem.
