    hammer2 - Stabilization pass
    
    * Fix numerous deadlocks in syncthr.
    
    * Fix startup issue in syncthr, elements in the initial iroot cluster
      were being marked INVALID for the syncthr.  This is what we want for
      front-end operations, but not for the syncthr.  The flag was preventing
      syncthr from properly synchronizing sub-trees.
    
    * Fix a chain leak in syncthr which was leaving referenced chains sitting
      around on unmount.
    
    * Do not repoint iroot elements in syncthr.  The iroot elements already
      exist and will not be created or destroyed, so no repointing should be
      necessary.
    
    * Fix improper freemap indirect block size in hammer2_chain_create_indirect().
    
    * Fix pmp->inode_tid assignment.  Inode number assignments are now handled
      on a per-PFS basis.
    
    * Use the data_count and inode_count statistics to fill out statfs and
      statvfs.
    
    * Use the data_count statistics to fill out vap->va_bytes for normal stat().
    
    * Cleanups
