The `struct zebra_ns` data structure is being used for both router information as well as support for the vrf backend( as appropriate ). This is a confusing state. Start the movement of `struct zebra_ns` into 2 things `struct zebra_router` and `struct zebra_ns`. In this new regime `struct zebra_router` is purely for handling data about the router. It has no knowledge of the underlying representation of the Data Plane. `struct zebra_ns` becomes a linux specific bit of code that allows us to handle the vrf backend and is allowed to have knowledge about underlying data plane constructs. When someone implements a *bsd backend the zebra_vrf data structure will need to be abstracted to take advantage of this instead of relying on zebra_ns.
