Optimize division operators handling of fractions

* libguile/numbers.c: (scm_euclidean_quotient, scm_euclidean_remainder,
  scm_euclidean_divide, scm_centered_quotient, scm_centered_remainder,
  scm_centered_divide): Optimize case where both arguments are exact and
  at least one is a fraction, by reducing to a subproblem involving only
  integers, and then adjusting the resulting remainder as needed.
