ECC Fixes.
* agent/cvt-openpgp.c (get_keygrip, convert_secret_key) (convert_transfer_key): Follow newer (>= 1.6) libgcrypt API, which does not distinguish the detail. (do_unprotect, convert_from_openpgp_main): Don't call map_pk_openpgp_to_gcry, as it's the value of libgcrypt API already and not the value defined by OpenPGP. (convert_to_openpgp): It's "ecc". * agent/gpg-agent.c (map_pk_openpgp_to_gcry): Remove. * g10/call-agent.c (agent_pkdecrypt): Fix off-by-one error. * g10/pubkey-enc.c (get_it): Fix swapping the fields error.
