Make GTK notebook log suppression opt-in to avoid a fatal error when the application calls g_log_set_writer_func() itself, as doing it more than once immediately kills the application with glib 2.73 and there is no way to check if it had been already done or not (you have to admire the purity of the API design here). This is unfortunate as 99% of the wxWidgets applications that do _not_ call g_log_set_writer_func() would now show the spurious diagnostics by default again, but preferable to making the remaining 1% crash, and there doesn't seem to be any other solution. Call the new GTKAllowDiagnosticsControl() function in the notebook sample to at least still avoid getting the spurious diagnostic messages described in #22176 there. See #22717. (cherry picked from commit 8af645ed229ebb2542769775565ce85c158e4fb1 and adapted to 3.2 stable ABI).
