refactor scale functions to allow re-use of their guts

This is the first of two patches to add rounding and ceiling versions of the
existing (truncating) functions _scale() and _scale_int() functions.  This
patch refactors the code, moving the wide integer multiplication and division
routines into stand-alone functions that can be reused to avoid duplication. 
This patch does not modify the exported API.

The division algorithms are replaced with versions that compute and return the
remainder as well as the quotient.  The remainder will be required, later, to
decide how to round the result, but is not currently used.
