    hammer2 - Sync thread work
    
    * Initial syncthread coding, still many issues to resolve, particularly
      with the handling of mirror_tid, but it was able to successfully
      synchronized a MASTER to a SLAVE.
    
    * Add more features to the hammer2_cluster*() API and structures and fix
      a couple of bugs in hammer2_cluster_lookup() and hammer2_cluster_next().
    
    * Add hammer2_cluster_next_single_chain() for advancing one element of
      a cluster structure.  Used to advance past a chain which the sync code
      must delete on a slave.
    
    * Fix a bug in hammer2_chain_lookup() when HAMMER2_LOOKUP_NOLOCK is used.
