	Merged from gtk-2-4:

	Fix #145470:

	* gtk/gtkfilechooserdefault.c
	(gtk_file_chooser_default_initial_focus): Queue a pending
	operation to select the first row if we are not finished loading
	yet.
	(gtk_file_chooser_default_class_init): Override GtkWidget::map().
	(gtk_file_chooser_default_map): New ::map() handler; refresh the
	file and bookmark lists.

	* gtk/gtkfilechooserdialog.c (gtk_file_chooser_dialog_class_init):
	Override GtkWidget::map() and GtkWidget::unmap().
	(gtk_file_chooser_dialog_constructor): Don't call initial_focus()
	here.
	(gtk_file_chooser_dialog_map): Map the file chooser widget if
	needed.  Call initial_focus() here.
	(gtk_file_chooser_dialog_unmap): Unmap the file chooser widget.
	When we are re-mapped, the widget will get mapped as well and it
	will have a chance to refresh.
