Reimplement scm_is_{un,}signed_integer for bignums
* libguile/integers.c (negative_int64):
(int64_magnitude):
(negative_uint64_to_int64):
(positive_uint64_to_int64):
(bignum_to_int64):
(bignum_to_uint64): New helpers.
(scm_integer_to_int64_z):
(scm_integer_to_uint64_z): New internal functions.
* libguile/integers.h: Declare internal functions.
* libguile/numbers.c (scm_is_signed_integer):
(scm_is_unsigned_integer): Simplify bigint cases.
