* tools/dbus-launch-x11.c (set_address_in_x11): fix from Michael
	Lorenz to use long not int with XChangeProperty format 32

	* dbus/dbus-sysdeps-util-unix.c
	(_dbus_write_pid_to_file_and_pipe): factor this out, and use the
	same code in _dbus_become_daemon (where the parent writes the pid
	file and to the pid pipe) and in bus_context_new (where the daemon
	writes its own pid file and to its own pid pipe)

	* bus/bus.c (bus_context_new): close the pid pipe after we print
	to it. Also, don't write the pid to the pipe twice when we fork,
	someone reported this bug a long time ago.
