    hammer2 - Major restructuring, part 6/several
    
    * Stabilization pass.
    
    * Protect vfs_sync with a master lock to serialize operations, to protect
      the master volume header sequencing.  The related fsync scan will use the
      same transaction id.
    
    * Fix a bug where races could cause SUBMODIFIED set in deep chains to not
      propagate back up to the root.
    
    * Limit debug dumps on unmount.
    
    * API adjustments.
