    hammer2 - flesh out inode and blockref chaining
    
    * Move the inode code into hammer2_inode.c
    
    * Rename ipstack to chain and do an initial skeleton in hammer2_chain.c
    
    * The hammer2_chain structures embed a blockref and maintain a chain
      of pointers all the way to the volume root.
    
      hammer2_chain structures are embedded in major hammer2 system memory
      structures (hammer2_inode, hammer2_mount, hammer2_indblock).
    
      All lookups and searches are tracked via hammer2_chain structures.
