    hammer2 - Get data-usage aggregation working, add INODE_GET
    
    * Cleanup aggregation of data_count and inode_count in the inode.
      data_count should now work properly (though it requires a 'sync'
      if you want up-to-date information).
    
      This allow data and inode usage for an entire sub-tree to be
      retrieved from the parent directory inode.  No need to run 'du'
      over millions of inodes.
    
      The new 'hammer2 stat' command can be used to access the info.
    
    * Add the HAMMER2IOC_INODE_GET/SET ioctls to access information that
      cannot be obtained from a normal stat().
