 Log Message:
 Invalidate rtcache based on a global generation counter
 
 The change introduces a global generation counter that is incremented when any
 routes have been added or deleted. When a rtcache caches a rtentry into itself,
 it also stores a snapshot of the generation counter. If the snapshot equals to
 the global counter, the cache is still valid, otherwise invalidated.
 
 One drawback of the change is that all rtcaches of all protocol families are
 invalidated when any routes of any protocol families are added or deleted.
 If that matters, we should have separate generation counters based on
 protocol families.
 
 This change removes LIST_ENTRY from struct route, which fixes a part of
 PR kern/52515.
