aarch64: h264 chroma motion compensation NEON optimizations
...
Since RV40 and VC-1 use almost the same algorithm so optimizations for
those two decoders are easy to do and included.

It does not help as an abstraction and adds dsputil dependencies.

vc1: make overlap filter for I-frames bit-exact.

Revert "VC1: merge idct8x8, coeff adjustments and put_pixels."
...
This reverts commit f8bed30d8b
. The reason
for this is that the overlap filter, which runs after IDCT, should run
on unclamped values, and thus IDCT and put_pixels() cannot be merged if
we want to attempt to be bitexact.

VC1: merge idct8x8, coeff adjustments and put_pixels.
...
Merging these functions allows merging some loops, which makes the
results (particularly after SIMD optimizations) much faster.
