  Log:
  Cleanup some dangling issues with cache_inval().  A lot of hard work went
  into guarenteeing that the namecache topology would remain connected, but
  there were two cases (basically rmdir and rename-over-empty-target-dir)
  which disconnected a portion of the hierarchy.
  
  This fixes the remaining cases by having cache_inval() simply mark the
  namecache entry as destroyed without actually disconnecting it from the
  topology.  The flag tells cache_nlookup() and ".." handlers that a node has
  been destroyed and is no longer connected to any parent directory.
  
  The new cache_inval() also now has the ability to mark an entire subhierarchy
  as being unresolved, which can be a useful feature to have.
