    hammer2 - xop stabilization - part 1/many
    
    * Create XOP threads on-demand, they are needed sometimes even on PFSs
      which don't normally need it.
    
    * For spmp roots, count PFSTYPE_SUPROOT as a master to simplify the cluster
      validation code.
    
    * Allow hammer2_inode_get() to only repoint part of an inode's cluster.
    
    * Stabilize the slave synchronizer (a little, requires more).
    
    * Remove more dead code.
