* dbus/dbus-server-unix.c (_dbus_server_new_for_domain_socket):
	save the domain socket name, and unlink it when we disconnect the
	server. Means that at least when we exit normally, we won't leave
	a bunch of junk in /tmp

	* dbus/dbus-transport-unix.c
	(_dbus_transport_new_for_domain_socket): code cleanup (nicer
	memory management). (I was making a real change here but then
	didn't)
