	Code review via regex "[^_l>p](malloc|free|realloc)\("
	* objects/fs/function.c : what's g_strdup() must be g_free()'d
	* plug-ins/dxf/dxf-import.c : use g_realloc()/g_free()
	* plug-ins/xfig/xfig-import.c : use g_free() instead of plain free()

	* app/filedlg.c(file_save_as_response_callback) : before destroying
	the save as dialog we need to drop the dialogs diagram reference.
	Fixes behaviour described in bug #123225#c7

	* app/interface.c(get_sheet_names) : need to sort sheets by their
	display name to really fix bug #160101.

	* objects/UML/association.c : dont leak the role_name calculated
	with visibility attribute, use g_strdup_printf() instead of strcat().

	* configure.in : fix typo in error message

	* lib/object.c : remove duplicated prototype
	* lib/element.c : element_update_connections_rectangle() assumes nine
	connection points, i.e. requires 'mainpoint'. g_assert() for this.
