Initialise VC1DSPContext for parser as well as for decoder.
Note, the VC-1 code doesn't actually use the function pointer yet.

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.

This reverts commit f8bed30d8b176fa030f6737765338bb4a2bcabc9. 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
results (particularly after SIMD optimizations) much faster.
