bring us closer to a complete nexthop verification that does NOT need

periodic scans:
-keep a tree of nexthops with valid/invalid flags
-provide kroute_match, which takes an IP address and gives the kernel route
 for that
-find the kernel route for a given nexthop with that
-keep a marker on the kernel route that a nexthop depends on it
-on removal of the kernel route, re-evaluate the affected nexthops for
 validity.
