I am not sure about the above Ipv6RoutingProtocol changes. It seems like
what you want to do is to get a handle on a static routing object and add a
host route directly, but you are instead providing a notification to all
routing protocols (as in RTM_NEWROUTE).

I've posted this repository on ns-3-reviews in case people would like to
review it there. Please review it by next Wed. or ask for more time; if no
major comments, I will try to merge this later next week.
