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

0e9d4a67f4 change qscale -> lambda for the motion estimation 
finetune bit/distortion weighting factor used in motion estimation, the old coeffs where finetuned relative to incorrect mv_penalty tables which where then fixed later but the coeffs where not
this _may_ fix the long standing blocking artifacts, but may also introduce mudding artefacts theoretically, so please tell us if u stumble across any so we can either fix them or export this variable so the user can change it
