    hammer2 - SPAN protocol work
    
    * Initial implementation of the LNK_SPAN protocol between two hammer
      service daemons running on different machines.  There's still lots to do.
    
      mount x P PFSs (P pipes)	(machine A)
    	|
      service daemon 		(machine A) (handling P + 1 connections)
    	|
      INET SOCKET
    	|
      service daemon		(machine B) (handling Q + 1 connections)
    	|
      mount x Q PFSs (Q pipes)	(machine B)
    
    * Service deamons starts with LNK_CONN and then interconnect SPANs.
    
    * SPAN protocol allows any number of connections between services daemons and
      from service daemons to physical HAMMER2 mounts.
    
    * Fixed a message write() sequencing bug
    
    * Added some additional debug directives, and also added a remote debug
      directive to connect from one already-running service daemon to another.
