VC-1 decoder with I-frames support and partial P-frames decoding
VC1 Intra blocks in P-frames use different zigzag table than I-frames.
Added loop filtering as ersatz for overlap filter (improves picture quality for coarse quantization).
This should make P-frames decoding work on x86 (by avoiding get_bits(0))
Some optimization and fixes - mostly reworked MC and bitplanes.
typo
Slightly reworked MC code, it gives better picture.
Use MpegEncContext->mbskip_table instead of custom bitplane.
Remove unused variable (and it wasn't free'd too)
0xFFFF l of cola. Now P-frames are decoded almost without distortions.

make state transition tables global as they are constant and the code is slightly faster that way
use ecx instead of cl (no speed change on P3 but might avoid partial register stalls on some cpus)
write cabac low and range variables as early as possible to prevent stalls from reading them before they where written, the P4 is said to disslike that alot, on P3 its 2% faster (START/STOP_TIMER over decode_residual)
moving lps state transition code a little up in the branched asm code (1% faster on P3)
slightly faster on P3 slightly slower on athlon and probably faster on P4

shift CABACContext.range right, this reduces the number of shifts needed in get_cabac() and is slightly faster on P3 (and should be much faster on P4 as the P4 except the more recent variants lacks an integer shifter and so shifts have ~10 times longer latency then simple operations like adds)
this code will not work with PIC as it needs 7 registers and gcc doesnt support that in PIC
