HAMMER Utilities: Sync with 58A

* Add the master=<number> mount option, a unique id (0-15) which uniquely
  identifies a master in a multi-master cluster.  It will initially be
  used to support multi-master mirroring.

* Rename the hammer softprune command to prune and remove the original
  prune.

* Transaction ids are no longer based on the time at all.  They used to
  be loosely based on the time but could get knocked off by bad system
  time.  Now they aren't at all.
