f3410b97cf introduced a regression on server
shutdown. If any button or key was held on shutdown (ctrl, alt, backspace
are usually still down) sending a raw event will segfault the server. The
the root windows are set to NULL before calling CloseDownDevices().
Avoid this by disabling all devices first when shutting down. Disabled
devices won't send events anymore.
Master keyboards must be disabled first, otherwise disabling the pointer
will trigger DisableDevice(keyboard) and the keyboard is removed from the
inputInfo.devices list and moved to inputInfo.off_devices. A regular loop
through inputInfo.devices would thus jump to off_devices and not recover.
