x86: dsputil: int --> ptrdiff_t for ff_put_pixels16_mmxext line_size param

This avoids SIMD-optimized functions having to sign-extend their
line size argument manually to be able to do pointer arithmetic.

split out ff_hwaccel_pixfmt_list_420[] over individual codecs.

Not all hwaccels implement all codecs, so using one single list for
multiple such codecs means some codecs will be represented in the list,
even though they don't actually handle that codec. Copying specific
lists in each codec fixes that.

svq3: fix decoding residual blocks of b-frames.

The residual block data of 16x16 blocks was ignored for b-frames, which
leads to easy-to-identify artifacts. After this patch, the artifacts are
gone. Sample video: svq3_watermark.mov. (Fate results unaffected.)
