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

avcodec/vdpau_mpeg4: fix order of quant matrix coefficients
The matrix coefficients are stored permutated for the IDCT,
rather then in plain raster order, and need to be un-permutated
for the hardware.

51efa68ec0 avcodec/vp3: Add missing check for av_malloc
Since the av_malloc() may fail and return NULL pointer,
it is needed that the 's->edge_emu_buffer' should be checked
whether the new allocation is success.

f442a376a1 checkasm: float_dsp: Scale FLT/DBL_EPSILON sufficiently when comparing
As the values generated by av_bmg_get can be arbitrarily large
(only the stddev is specified), we can't use a fixed tolerance.

This matches what was done for test_vector_dmul_scalar in
38f966b2222db.

This fixes the float_dsp checkasm test for some seeds, when built
with clang for mingw/x86_32.

a4ba6e7d2c 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).
