Fix XvMC. XvMCCreateBlocks() may not allocate 16-byte aligned blocks,
so we can't use SSE-optimized routines.

r20739 broke compilation on systems without yasm

refactor and optimize scalarproduct
29-105% faster apply_filter, 6-90% faster ape decoding on core2
(Any x86 other than core2 probably gets much less, since this is mostly due to ssse3 cachesplit avoidance and I haven't written the full gamut of other cachesplit modes.)...

port ape dsp functions from sse2 to mmx
now requires yasm

Drop unused args from vector_fmul_add_add, simpify code, and rename

The src3 and step arguments to vector_fmul_add_add() are always zero
and one, respectively. This removes these arguments from the function,
simplifies the code accordingly, and renames the function to better...

Do not check for both CONFIG_VC1_DECODER and CONFIG_WMV3_DECODER,
the former depends upon the latter.

Do not redundantly check for both CONFIG_THEORA_DECODER and CONFIG_VP3_DECODER.
The Theora decoder depends on the VP3 decoder.

avg_ pixel functions need to use (dst+pix+1)>>1 to average with existing
pixels, not (dst+pix)>>1.
This makes the mmx functions bitexact with the C functions.

libavutil uses this naming scheme already.
