[FFmpeg-cvslog] avcodec/atrac3plus: reorder channels to match the output layout

avcodec/atrac3plus: reorder channels to match the output layout
The order in which the channels are coded in the bitstream do not always follow
the native, bitmask-based order of channels both signaled by the WAV container
and forced by this same decoder. This is the case with layouts containing an
LFE channel, as it's always coded last.
Fixes ticket #9964.

Also, there are no channels that correspond to a side element in this

[FFmpeg-cvslog] swscale: aarch64: Fix yuv2rgb with negative strides

swscale: aarch64: Fix yuv2rgb with negative strides
Treat the 32 bit stride registers as signed.
Alternatively, we could make the stride arguments ptrdiff_t instead
of int, and changing all of the assembly to operate on these
registers with their full 64 bit width, but that's a much larger
and more intrusive change (and risks missing some operation, which
would clamp the intermediates to 32 bit still).

swscale: aarch64: Fix yuv2rgb with negative strides
Treat the 32 bit stride registers as signed.
Alternatively, we could make the stride arguments ptrdiff_t instead
of int, and changing all of the assembly to operate on these
registers with their full 64 bit width, but that's a much larger
and more intrusive change (and risks missing some operation, which
would clamp the intermediates to 32 bit still).
Fixes: https://trac.ffmpeg.org/ticket/9985
Signed-off-by: Martin Storsjö
(cherry picked from commit cb803a0072cb98945dcd3f1660bd2a975650ce42)
