    hammer2 - wire up msg transaction state machine
    
    * Wire up the msg transaction state machine.  Split hammer2_msg into
      hammer2_state and hammer2_msg.  Track states in two RB trees in the
      hammer2_pfsmount structure.
    
      Handle CREATE, DELETE, ABORT, and REPLY flags.
    
    * Revamp the API.  The adjustments make it less likely that messages can
      be left dangling.
    
    * Compile only, untested, not yet operational.
