    Mass api change from GtkExtendedLayout --> GtkSizeRequest
    
    This commit makes a few massive changes to the extended layout
    code:
      a.) gtkextendedlayout.c --> gtksizerequest.c
      b.) _is_height_for_width --> get_request_mode()
      c.) get_desired_size(), get_desired_width(), get_desired_height() -->
          get_size(), get_width(), get_height()
    
    This is the first partial commit and only effects portions
    of the tree that have already been merged in master (in order to
    easily cherry pick this commit).
