* rsa.c (rsa_init_private_key, rsa_clear_private_key): Handle d.

* rsa.c (rsa_check_size): Changed argument to an mpz_t. Updated
callers.
(rsa_prepare_private_key): Compute the size of the key by
computing n = p * q.

* rsa.c (rsa_check_size): New function, for computing and checking
the size of the modulo in octets.
(rsa_prepare_public_key): Usa rsa_check_size.
(rsa_init_private_key): Removed code handling n, e and d.
(rsa_clear_private_key): Likewise.
(rsa_compute_root): Always use CRT.
