    HAMMER VFS - version 2 work - move directory entries to inode localization
    
    * Set version 2 features.  Directories created in a version 2 HAMMER
      filesystem place their directory entries in the B-Tree's inode localization
      space instead of the general space.  Pre-existing directories continue
      to use the old scheme.
    
    * Amost doubles directory lookup / find / ls performance in effected
      directories.  However, at the moment the B-Tree must be reblocked before
      the gains are seen.
