9d8ecdd8ca vc-1: Add platform-specific start code search routine to VC1DSPContext.
Initialise VC1DSPContext for parser as well as for decoder.
Note, the VC-1 code doesn't actually use the function pointer yet.

319235c67c vc1dsp: introduce cases for 8x8 and 16x16
This allows further unrolling the DSP implementation where possible.

x86 and ARM DSP modified by simply moving the multiple calls from vc1dec
to the DSP code. Decoding improvements should only occurs because of the
compiler actually able to unroll more.

Decoding time: ~8.80s -> 8.64s (ie around 2%)

71617884a2 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.

18b6a69ce9 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.

Merging these functions allows merging some loops, which makes the
