    hammer - Use new vsyncscan() mechanic.
    
    * Use the new vsyncscan() mechanic, greatly reducing the work involved
      in finding dirty vnodes in hammer_vfs_sync() and during unmounting.
      Call vsyncscan() instead of vmntvnodescan().
    
    * We set VISDIRTY in the vnode and call vn_syncer_add() when an inode
      becomes dirty.  This ensures that dirty vnodes are placed in the syncer
      list even if the vnode has no related dirty file data buffers.
    
      Previously we had to do a full scan of the mount's vnode list to
      find dirty inodes.
