gpg: Convey --quick option to dirmngr for --auto-key-retrieve.

Browse Source 
* g10/call-dirmngr.c (gpg_dirmngr_ks_get): Add arg 'quick'.
(gpg_dirmngr_wkd_get): Ditto.
* g10/keyserver.c (keyserver_get): Add arg 'quick'.
(keyserver_get_chunk): Add arg 'quick'.
(keyserver_import_fprint): Ditto.  Change callers to pass 0 for it.
(keyserver_import_keyid): Ditto.
(keyserver_import_wkd): Ditto.
* g10/mainproc.c (check_sig_and_print): Call the 3 fucntions with
QUICK set.
--

Note that this option has not yet been implemented by dirmngr.
Dirmngr will simply ignore it for now.
