Add support for a destructor for ui_out data and use it to
provide a ui_out destructor. * ui-out.h: Declare the new ui_out destructor. (ui_out_impl): Add a field for data destructor in ui_out_impl. * ui-out.c (default_data_destroy): Add a default data destructor which does nothing. (default_ui_out_impl): Set the new data_destroy field to default_data_destroy (uo_data_destroy): Local function which invokes the data destructor if present. (clear_table): Local function which clears the table data of a ui_out object. (ui_out_destroy): Public function which frees a ui_out object. (ui_out_table_end): Use the new clear_table function. * cli-out.c (cli_ui_out_impl): Set the new data_destroy field to NULL. * mi/mi-out.c (mi_ui_out_impl): Set the new data_destroy field to NULL.
