Alterantivly to this it is possibly to allocate a bigger array

Note: oss-fuzz assigned this issue to a unrelated theora bug so the bug number matches that

avcodec/utils: allocate a line more for VC1 and WMV3
Fixes: out of array read on 32bit
Fixes: 54857/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_VC1_fuzzer-5840588224462848

The chroma MC code reads over the currently allocated frame.
Alternative fixes would be allocating a few bytes more at the end instead of a whole
line extra or to adjust the threshold where the edge emu code is activated

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.
