773d1b857b avcodec/pictordec: Remove mid exit branch 
This causes the RLE decoder to exit before applying the last RLE run
All images i tested with are unchanged, this makes the special case
for handling the last run unused for non truncated images.

0891a36dd8 swscale/input: Use more unsigned intermediates 
Same principle as previous commit, with sufficiently huge rgb2yuv table
values this produces wrong results and undefined behavior.
The unsigned produces the same incorrect results. That is probably
ok as these cases with huge values seem not to occur in any real
use case.

a1f13b592b 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).
