	passed a user, and returns the connection.
	(do_handle_userauth): When a service is eventually invoked, it is
	passed a single argument: the connection. Previously, the user
	object was passed as argument to the service.
	(do_userauth): Clear the user attribute of the connection, and
	display a warning message if the connection was already
	authenticated.
	(do_userauth): Don't call make_userauth_continuation() here.
