    Update git submodules
    
    * Update swift from branch 'master'
      - Merge "wsgi: Ensure _response_headers is a list"
      - wsgi: Ensure _response_headers is a list
    
        It's reasonably common that apps or middlewares may send back headers
        via dict.items(), but WSGIContext users often expect the headers to be
        a list.  Convert it for them, to avoid errors like
    
            AttributeError: 'dict_items' object has no attribute 'append'
