    hammer2 - Refactor frontend part 2/many
    
    * Move the CHAIN_UNLINKED flag to INODE_ISUNLINKED.
    
    * This allows the removal of hammer2_cluster_isunlinked(),
      hammer2_cluster_set_chainflags(), and hammer2_cluster_clr_chainflags().
    
    * Greatly simplifies hammer2_vop_inactive(), in particular removes a
      cluster lock and related I/O.
    
    * Greatly simplifies hammer2_vop_reclaim(), in particular removes a
      cluster lock and related I/O.
