ccff9da62a H261 fixing and cleaning:
-corrected wrong value in mv data
 -set correct mb_type after adjusting index
 -don't use H263 loop filter when the loop filter flag is set but when
  using the H261 encoder
 -use the same unquantizer as H263 (which is optimized btw)
 -removed unused members in H261Context

49e5dcbce5 H.261 decoder improvements
- GOB's can exist of only MBA_STUFFING codes: it crashed before, but it is fixed now
- Clearer code
- Some extra checks so the decoder is more resilient against errors
