    hammer2 - Starting refactoring PFS management in mount
    
    * Start removing single-device shims.
    
    * Adjust data structures.  Rename hammer2_mount to hammer2_dev and
      rename hammer2_pfsmount to hammer2_pfs.  Refactor unmount.
    
    * Integrate all available PFSs when a block device is mounted and
      De-integrate related PFSs when a block device is unmounted.
    
      At least one PFS (typically @LOCAL) must be mounted from a HAMMER2 block
      device for that device's PFSs to be used.  At least for now.  We could
      eventually trigger auto-mounting via the probe code.
    
    * Add a synchronization thread abstraction for a PFS.
    
    * Normalize chain->pmp to NULL for any chain which is part of the super-root
      topology, for later sanity assertions.
    
    * The ioctl to create a PFS now adds it (delete and snapshot do not, yet).
