MonitorManager: emit a DBus signal when we change the display configuration
Using out-of-band notifications from the wayland protocol or from
X is racy, in that the client could ask for the new resources before
we have them.
Instead, with a signal, we are sure that when the client asks for
it, it will get the right values.
