Fix non-portable usage of `isinf' in `max' and `min'

* numbers.c: Add new macros DOUBLE_IS_POSITIVE_INFINITY and
  DOUBLE_IS_NEGATIVE_INFINITY.
  (scm_max, scm_min): Use the new macros to detect particular
  infinities.  Previously we checked the return value of `isinf'
  to determine the sign of the infinity, but that is not portable.
