required for a corner case in dec_hash() in the following commit and also usually faster. dec_hash() needs some extra precision above MPD_MAX_PREC, and _mpd_base_ndivmod() is not audited for that. 2) Use _mpd_basemul() if the length of the smaller operand is less than or equal to 256. While this is technically an optimization, it is required for *testing* corner cases in dec_hash() in reasonable time.
