As a side effect it will also decode a lot of P-frames from those.

This should fix chroma issues in WMV3/VC-1 decoder with avfilter enabled.

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.

MPV_common_init(), so calling both is redundant and leads to memory
leaks in WMV3/VC-1 decoder. Thus use only the first function in
WMV3/VC-1 decoder initialization.

VLC tables should only be initialized from one place.
This initializes/calculates more VLC tables than necessary for VC1 decoding,
but this is only done once and only a small overhead in time and space (maybe
30 kB) it seems not worth adding a separate function.

These are only supposed to be called once per row, not once per macroblock.

~8% faster VC-1 decoding.
Possible future optimization: clear blocks after use instead of before, and for
DC-only blocks, only clear the DC coefficient.

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).
