* commit 'e5ffffe4': h264chroma: Remove duplicate 9/10 bit functions x86: Use simple nop codes for <= sse (rather than <= mmx) vp56: Remove clear_blocks call, and clear alpha plane U/V DC only Merged-by: NMichael Niedermayer <michaelni@gmx.at>

change the treatment of the strip y coordinates which previously did not follow the description (nor did it behave like the binary decoder on files with absolute strip offsets). Signed-off-by: NMichael Niedermayer <michaelni@gmx.at>

The new code is also faster and more robust. As for the performance: old decoder + conversion to rgb: fps = 2618 old decoder, without converting to rgb: fps = 4012 new decoder, producing rgb: fps = 4502 Signed-off-by: NMichael Niedermayer <michaelni@gmx.at>

The non-intra-pcm branch in hl_decode_mb (simple, 8bpp) goes from 700 to 672 cycles, and the complete loop of decode_mb_cabac and hl_decode_mb (in the decode_slice loop) goes from 1759 to 1733 cycles on the clip tested (cathedral), i.e. almost 30 cycles per mb faster.

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.) Signed-off-by: NMichael Niedermayer <michaelni@gmx.at>

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. Signed-off-by: NMichael Niedermayer <michaelni@gmx.at>

Instead, only extend edges on-demand when the motion vector actually crosses the visible decoded area using ff_emulated_edge_mc(). This changes decoding time for cathedral from 8.722sec to 8.706sec, i.e. 0.2% faster overall. More generally (VP8 uses this also), low-motion content gets significant speed improvements, whereas high-motion content tends to decode in approximately the same time.
