gpg: New option --default-new-key-algo.
* common/openpgp-oid.c (openpgp_is_curve_supported): Add optional arg R_ALGO and change all callers. * common/util.h (GPG_ERR_UNKNOWN_FLAG): New error code. * g10/options.h (struct opt): Add field DEF_NEW_KEY_ALGO. * g10/gpg.c (oDefaultNewKeyAlgo): New enum. (opts): New option "--default-new-key-algo". (main): Set the option. * g10/keygen.c: Remove DEFAULT_STD_ FUTURE_STD_ constants and replace them by ... (DEFAULT_STD_KEY_PARAM, FUTURE_STD_KEY_PARAM): new string constants. (get_keysize_range): Remove arg R_DEF and return that value instead. Change all callers. (gen_rsa): Use get_keysize_range instead of the removed DEFAULT_STD_KEYSIZE. (parse_key_parameter_part): New function. (parse_key_parameter_string): New function. (quick_generate_keypair): Refactor using parse_key_parameter_string. (generate_keypair): Ditto. (parse_algo_usage_expire): Ditto.
This new option is intended to be used in the forthcoming
--set-profile command of gpgconf. It allows to provide a gpg
configuration with custom defaults for a new key using the simple
commands which use the default algorithm set.
