Subject: wks: Use dedicated type to convey user ids.

* tools/gpg-wks.h (uidinfo_list_s, uidinfo_list_t): New.
* tools/wks-util.c (append_to_uidinfo_list): New.
(free_uidinfo_list): New.
(wks_list_key): Change arg r_mboxes to uidinfo_list_t.  Use
append_to_uidinfo_list.
* tools/gpg-wks-server.c (sserver_ctx_s): Replace strlist_t by
uidinfo_list_t.
(process_new_key): Ditto.
(check_and_publish): Ditto.
(command_receive_cb): Replace free_strlist by free_uidinfo_list.
* tools/gpg-wks-client.c (command_check): Replace strlist_t by
uidinfo_list_t.  Also print user id in verbose mode.
