Clean up scm_sum
* libguile/integers.h:
* libguile/integers.c (scm_integer_to_double_z):
(scm_integer_add_ii, scm_integer_add_zi, scm_integer_add_zz): New
internal functions.
* libguile/numbers.c (sum): New helper for scm_sum. Clean up to avoid
repetition. The dispatch is less optimal but the code is shorter and
more maintainable; in any case if speed is important, the compiler needs
to be involved.
(scm_sum): Adapt.
