* bus/bus.c (setup_server): fix this so dbus-daemon-1 doesn't
	crash on startup. Need to get "try starting the daemon"
	in the test suite I guess. ;-)

	* dbus/dbus-server.h, dbus/dbus-server.c: remove the stuff that
	tracked the number of open connections; it's better done in
	application-specific code as you want it to span all servers etc.
