    hammer2 - cluster / libdmsg circuit work
    
    * Major work on the virtual circuit code.  Note there are still some thread
      races.
    
    * Major work on the spanning tree code to allow for future symmetric
      pathing support.
    
    * fs_label is now part of the RB tree compare, along with pfs_fsid.
      (e.g. the serial number for BLK protocol services).
    
    * Rip out the 'router' structure, replace with the 'circuit' structure.
      Embed circuit0 in the iocom.
