    hammer2 - Add directive to destroy bad directory entries
    
    * Add a directive and ioctl that is capable of destroying bad hammer2
      directory entries.  If topological corruption occurs due to a crash
      (which theoretically shouldn't be possible with HAMMER2), this directive
      allows you to destroy directory entries which do not have working inodes
      and cannot otherwise be destroyed with 'rm'.
    
    * Sysops should only use this directive when absolutely necessary.
