Cleanup wrt ipassign_wrapper and interaction with static routing since ipassign_wrapper no longer does that. Revert back to always invoking the static route calculator (which figures out what to do). Remove the stiff about generating a linkmap, which was an interim measure for ddijk routing; now done with gentopfile.
