RV40: reuse some H.264 motion compensation functions in RV40.

Browse Source 
Since RV40 is based on H.264, it uses the same interpolation filters and
functions for halfpel interpolation in one direction can be reused.
Unfortunately other cases are implemented differently and produce slightly
different output because of rounding.
