    world - Fix fstat and gcore
    
    * fstat needs to iterate vm_map_entry's
      via the RB tree, but it isn't entirely trivial because we
      have to kread().
    
    * gcore needs to steal a different field for its iterator
      when building a map from procfs.
    
    * Fixes buildworld.
