Also add mmxext versions of vsad8 and vsad_intra8, and sse2 versions of
vsad16 and vsad_intra16.
Since vsad8 and vsad16 are not bitexact, they are accordingly marked as
approximate.

Also add a missing c->pix_abs[0][0] initialization, and sse2 versions of
sad16_x2, sad16_y2 and sad16_xy2 (%15 to %20 faster than mmxext).
Since the _xy2 versions are not bitexact, they are accordingly marked as
approximate.

This makes the init files match the structure of the dsputil split.

The remaining dsputil bits are encoding-specific anyway.

The SSE version has been no different than the mmx one since commit a41bf09dSigned-off-by: James Almer <jamrial@gmail.com>

Also shorten HuffYUV context member names to avoid clutter.

Some codecs still use mmx versions, so have them use the versions
with newer instruction sets.

XvMC has long ago been superseded by newer acceleration APIs, such as
VDPAU, and few downstreams still support it. Furthermore XvMC is not
implemented within the hwaccel framework, but requires its own specific
code in the MPEG-1/2 decoder, which is a maintenance burden.

This decreases the diff to libav
