    Fix some more compiler warnings.
    
    * libgda/gda-data-model.c: (gda_data_model_set_values): Fix a
      signed/unsigned warning.
    * libgda-ui/data-entries/gdaui-entry-bin.c: (popup_position):
      Remove the call to
      gtk_widget_size_request() because the result is not used.
    * libgda-ui/data-entries/widget-embedder.c:
      (widget_embedder_size_allocate): Remove the call to
      gtk_widget_get_child_requisition() because the result is not used.
