NetworkManager's D-Bus service.  We call its state() method at startup
to get the current network state, and listen for StateChanged signals
thereafter.

The code is here:

If some parts look complex it's only because we're using raw libdbus
calls.  The logic should get much simpler once it's ported to GDBus.
