[Murray Cumming <murrayc src gnome org>]

commit 2f35ec1224ef15a2109687ccfca0dc74ff73017d
Author: Murray Cumming <murrayc murrayc com>

    libglom::LayoutItem_Portal: Added get_suitable_table_to_view_details().
    
    	* glom/base_db.[h|cc]: Move the get_portal_navigation_relationship_automatic()
    	and get_suitable_table_to_view_details() utility functions to:
    	* glom/libglom/data_structure/layout/layoutitem_portal.[h|cc]: Also
    	move other privately-used utility functions here too, from Base_DB.
    	* glom/mode_design/layout/dialog_layout_calendar_related.cc: update_ui():
    	* glom/mode_design/layout/dialog_layout_list_related.cc: update_ui():
    	* glom/mode_data/box_data_portal.cc:
      get_has_suitable_record_to_view_details(),
      get_has_suitable_record_to_view_details(): Adapted.
