  HAMMER 65/Many: PFS cleanups and confusion removal
  
  * Simplify master/slave operation.  Remove the master=, slave, and no-mirror
    options from pfs-update.  Retain pfs-master, pfs-slave, pfs-upgrade, and
    pfs-downgrade for dealing with master and slave operation.
  
    Move the master= and nomirror specifications back to hammer_mount.  They
    have to be mount-wide anyhow, the current code does not support different
    master ID's on a PFS-by-PFS basis.
  
  * Add some additional failsafes to the mount code.   The master id cannot
    be allowed to change by a mount update (-u).
  
  * Fix a bug in hammer pfs-upgrade operation that could result in a livelock
    during the B-Tree iteration.
