    hammer2 - Implement most of the hammer2_chain_*() function set
    
    * Implement hammer2_chain_push/first/next/get/link/unlink.  Integrate
      the hammer2_inode into the chain topology.
    
    * Route both the reference count and the busy count through the chain
      structure.
    
    * Implement simplified I/O via the chain functions.
    
    * Indirect blocks not yet implemented in the chain functions.
    
    * Use the chain functions to locate both the super-root inode and the
      root-inode via its label.
