Implement round-quotient with new integer lib
* libguile/integers.c (scm_integer_round_quotient_ii)
(scm_integer_round_quotient_iz, scm_integer_round_quotient_zi)
(scm_integer_round_quotient_zz): New internal functions.
(integer_round_quotient_zz): New helper.
(long_sign, bignum_cmp_long): New helpers.
* libguile/integers.h: Declare internal functions.
* libguile/numbers.c (scm_round_quotient): Use the new functions.
(scm_i_bigint_round_quotient): Remove unused helper.
