gpg: Fix the use of future-default with --quick-add-key.
* g10/keygen.c (parse_key_parameter_part): Add arg clear_cert. (parse_key_parameter_string): Add arg suggested_use and implement fallback. Change callers to pass 0 for new arg. (parse_algo_usage_expire): Pass the parsed USAGESTR to parse_key_parameter_string so that it can use it in case a subkey is to be created.
The problem here was that future-default gives the primary and subkey
algorithm. However, when using future-default for adding a key, the
second part was always used which is for encryption. If the caller
now wanted to create a signing subkey using the future-default
parameters this did not worked.
gpg --batch --passphrase "" --quick-add-key FPR future-default encr
aready worked as did
gpg --batch --passphrase "" --quick-add-key FPR ed25519 sign
but
gpg --batch --passphrase "" --quick-add-key FPR future-default sign
does only work with this fix.
