For rounding in chroma MC SSSE3, use 16-byte pw_3/4 instead of reading 8 bytes
and then using movlhps to dup it into the higher half of the register.

MMX, MMX2, SSE2 and SSSE3 optimizations for pred16x16/8x8_plane H264 intra
prediction (plus some with different rounding for svq3/rv40). Speedup (for
SSSE3) about ~6-fold, 3.6% faster overall with cathedral sample.

format), LGPL'ed with permission from Jason and Loren. This includes mmx2
code, so remove inline asm from h264dsp_mmx.c accordingly.

still #included in dsputil_mmx.c and is part of DSPContext, and h264dsp_mmx.c,
which represents H264DSPContext and is now compiled on its own.

Move H264 dsputil functions into their own struct

This moves the H264-specific functions from DSPContext to the new
H264DSPContext. The code is made conditional on CONFIG_H264DSP
