4bbe788ab7 Add pts field to AVSubtitle, for use by future XSUB encoder (and XSUB decoder 
should use it, too).

351653a51e VC-1/WMV: Remove redundant ff_init_block_index() calls. 
These are only supposed to be called once per row, not once per macroblock.
~1.5% faster according to oprofile.

010f98f96a VC-1/WMV3 decoding: don't clear blocks unless they're actually used. 
~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.

4f717c69ed idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall. 
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).
