  HAMMER 58A/Many: Mirroring support part 1
  
  * Implement mastership domains for transaction ids to support multi-master
    mirroring and implement mastership selection at mount time.
  
    Mastership domains work by having the low 4 bits of the transaction id
    specify the mastership id (0-15).  This allows the mirroring code to
    distinguish between changes originating on a particular node and changes
    mirrored from another node.
  
    This also ensures that filesystem objects can be created on the mirrors
    in parallel without resulting in conflicitng object ids.
  
  * Eliminate time-based TID generation.  Just increment the TID as
    appropriate.
  
    NOTE: Portions of this change may be reverted at a later time depending
    on how the mirroring implementation proceeds.
  
  * Minor code cleanups.
