    hammer2 - Start adding internal cluster API
    
    Initial addition of the cluster API.  H2 will be non-operational until this
    is stabilized.  Adding the cluster API will require a few stages.  This first
    stage is to add the API and make it work under degenerate (single-target)
    conditions.
    
    The hammer2_cluster structure collects and manages an array of up to
    8 chains representing mirrors / cluster nodes / copies of the same point
    in the topology.
    
    * Add hammer2_cluster.c, and hammer2_cluster_t
    
    * Replace nearly all high-level (vnops, vfsops) chain calls with
      cluster calls.
