	* src/mpwrap.[ch]: fix the gmp accessors

	* src/mpzextra.[ch], src/funclib.c, lib/number_theory/factoring.gel:
	  snarf the Pollard-Rho implementation from gmp examples and use it
	  for a built in version of Factorize, and whack the gel one and
	  also whack FactorizeLoopMax as it doesn't make sense now.  Also
	  add possibility to interrupt the primality tests (except when
	  inside mpz_millerrabin).

	* src/eval.c: if an interruption is raised during a built in
	  function call, then raise exception.
