Brad Fitzpatrick 04c2c5bd80 net/interfaces: define DefaultRouteInterface and State.DefaultRouteInterface 
It was pretty ill-defined before and mostly for logging. But I wanted
to start depending on it, so define what it is and make Windows match
the other operating systems, without losing the log output we had
before. (and add tests for that)
