mpi: put access macros into mp_ namespace

* mpi/mpi.h (mp_sign, mp_isneg, mp_used, mp_alloc, mp_digits,
mp_digit): New macros, based on renaming SIGN, ISNEG, USED,
ALLOC, DIGITS and DIGIT.
(mp_set_prec): Use mp_digits instead of DIGITS.

* mpi/mpi.c (SIGN, ISNEG, USED, ALLOC, DIGITS, DIGIT): Macros
defined here now, as local aliases for their namespaced
counterparts.

* arith.c (signum, floordiv): Replace ISNEG with mp_isneg.

* rand.c (random): Replace ISNEG with mp_isneg.

* sysif.c (off_t_num): Replace USED, DIGITS and ISNEG with
mp_used, mp_digits and mp_isneg.
