Limit intermediate precision bits correctly

The intermediate precision must be correctly
limited since the current implementation stores
the intremidiate filtered data in signed 16 bit
buffers. Therefore for n-bit sources, the intermediate
extra precision bits must be at most 15-n.

This is now needed since the intermediate extra
precision is now an user configurable parameter.
