gpg: New command --locate-external-key.

* g10/gpg.c (aLocateExtKeys): New.
(opts): Add --locate-external-keys.
(main): Implement that.
* g10/getkey.c (get_pubkey_byname): Implement GET_PUBKEY_NO_LOCAL.
(get_best_pubkey_byname): Add arg 'mode' and pass on to
get_pubkey_byname.  Change callers.
* g10/keylist.c (public_key_list): Add arg 'no_local'.
(locate_one): Ditto.  Pass on to get_best_pubkey_byname.
--

This new command is a shortcut for

  --auto-key-locate nodefault,clear,wkd,... --locate-key

and uses the default or configured AKL list but does so without local.
