    hammer2 - Major restructuring, part 2/several
    
    * Stabilization pass on hammer2_inode_connect() and
      hammer2_hardlink_consolidate().  Adjust the API to accomodate
      requirements (primarily that the caller is responsible for holding
      the inode locked and for replacing ip->chain).
    
    * Add hammer2_inode_repoint() to handle the guts of replacing ip->chain.
    
    * Flush code shouldn't be messing the chain->bref when deleting the chain
      as the chain may be used in a duplication operation after the call.
    
    * basic rm/mv/ln operations now work (note: we still need to code the
      reparenting of sub-chains based on chain->duplink, and hardlinks are
      still buggy when parent directories get renamed).
