This helps detecting inconsistencies in swscale input/output code and
a av_read_image_line()/av_write_image_line() pass.

Ensure those bits are copied, which will result in the output being the same as
the input, where swscale set them to the equivalent of fully opaque.

This made the output non binary reproducible across different versions of
zlib.

The demuxer's 'missing_streams' private option is used to communicate
information from the demuxer to avformat_find_stream_info(). However,
that is not only unnecessarily complicated, it also leaks internal
information to users, e.g. this option appears in the results of the
fate-flv-demux test.
Use a new field in FFFormatContext to communicate this information
instead.
stddev and PSNR values change by the removal of format conversion and because
of the added sws_flags. Either or will have the same effect even on their own.

This format is useful for doing certain lossless transforms on images,
RCT in particular, which require you to escalate the size from 16 to
32 bits to avoid overflows.
APIchanges will be done alongside when comitting.
FATE results differ when using the original zlib and zlib-ng.
Since we don't need to test the result from zlib itself, this commit
disables compression on tests for zlib-based codecs, which ends up
giving the same results with both libraries.

md5 values change because the nut container now reports rawvideo as encoder
and Y410 as codec type instead of the bogus RGB[15].

There's no need to keep using a custom decoder for this pixel format.

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.
