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

This ensures that these functions are inlined into the per-position
entry points, allowing constant propagation as needed for proper
optimisation.
18% faster VC1 decoding on Cortex-A9.

Results of IDCT can by far outreach the range of ff_cropTbl[], leading
to overreads and potentially crashes.

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.
This removes duplicated definitions of 8x8 and 16x16 fullpel MC
functions with various names reducing dsputil.o by 8k on x86_64.

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

Includes mmx2 asm for the various functions.
Note that the actual idct still does not have an x86 SIMD implemtation.
For wmv3 files using regular idct, the decoder just falls back to simple_idct,
since simple_idct_dc doesn't exist (yet).

Otherwise doxygen complains about ambiguous filenames when files exist
under the same name in different subdirectories.
