    hammer2 - initial mkdir skeleton
    
    * Code up VOP_NMKDIR() to test the chain creation code and VOP_READDIR.
    
    * Code up VOP_NLOOKUPDOTDOT.
    
    * Adjust newfs_hammer2 to set alloc_tid to 16, so we can reserve some
      inode numbers for the super-root and root.
    
    * Add another field to the media inode_data for inode allocation within
      a PFS.
    
    Note: These are mostly skeletons.  We don't flush modified chain elements
          back to the disk yet and the chain create path can't create indirect
          blocks yet.
