Export converting mpz to [u]intmax
This refactoring will help improve timestamp handling later
(Bug#32902).
* src/bignum.c (mpz_set_uintmax): Move to bignum.h,
and make inline.
(mpz_set_uintmax_slow): Now extern.
(mpz_to_intmax, mpz_to_uintmax): New functions, with
implementation taken from the old bignum_to_intmax
and bignum_to_uintmax.
(bignum_to_intmax, bignum_to_uintmax): Use them.
