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)...

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
