* options.skel: Use new hkp://subkeys.pgp.net as sample keyserver since

they at least handle subkeys correctly.

* options.h, g10.c (main), main.h, keylist.c (show_keyserver_url),
mainproc.c (check_sig_and_print), parse-packet.c (dump_sig_subpkt,
parse_one_sig_subpkt, can_handle_critical): Add read-only support for
preferred keyserver subpackets.  They're basically policy URLs with a
different name.  Add a verify-option "show-preferred-keyserver" to turn
them on and off (on by default, as per stable branch).

* g10.c (main): Add "--set-notation" as alias to "--notation-data" this is
to make things consistent with --set-policy-url meaning both sigs and
certs.
