** This is a collection of miscellaneous utility functions that aren't
** logically part of a larger package of routines. All functions defined in
** this file must be prefixed with inn_ (and constants and macros, if any,
** must be prefixed with INN_). The only exception are the macros handled by
** <inn/defines.h>.

digit; upper- and lower-case digits are allowed. If there are an uneven
number of input characters, the input is zero-padded at the end (so the
