gpg: Allow fingerprint based lookup with --locate-external-key.
* g10/keyserver.c (keyserver_import_fprint_ntds): New. * g10/getkey.c (get_pubkey_byname): Detect an attempt to search by fingerprint in no_local mode.
See the man page. For testing use
gpg --auto-key-locate local,wkd,keyserver --locate-external-key \ FINGERPRINT
with at least one LDAP keyserver given in dirmngr.conf. On Windows
"ntds" may be used instead or in addtion to "keyserver".
