Give greeter and slave access to display independent of hostname.

	Give greeter and slave access to display
	independent of hostname.

	* daemon/gdm-slave.c
	(gdm_slave_connect_to_x11_display):
	XSetAuthorization before XOpenDisplay so
	that the slave can connect even if hostname
	changes.  Call XAddHosts after XOpenDisplay
	so that clients run by the slave and the
	greeter can connect even if the hostname
	changes.
