gpg: Default to SHA-512 for all signature types on RSA keys.
* g10/main.h (DEFAULT_DIGEST_ALGO): Use SHA512 instead of SHA256 in
--gnupg mode (leave strict RFC and PGP modes alone).
* configure.ac: Do not allow disabling sha512.
* g10/misc.c (map_md_openpgp_to_gcry): Always support SHA512.
--
SHA512 is more performant on most 64-bit platforms than SHA256, and
offers a better security margin. It is also widely implemented.
