* TODO: Removed the "extra widget" bit, implemented with the
following:
* gtkfilechooser.h: Added gtk_file_chooser_{set,get}_extra_widget().
* gtkfilechooser.c (gtk_file_chooser_base_init): Install an
"extra-widget" interface property.
(gtk_file_chooser_set_extra_widget): Implemented.
(gtk_file_chooser_get_extra_widget): Implemented.
* gtkfilechooserutils.h (GtkFileChooserProp): Added
GTK_FILE_CHOOSER_PROP_EXTRA_WIDGET.
* gtkfilechooserutils.c (_gtk_file_chooser_install_properties):
Added the "extra-widget" property.
* gtkfilechooserimpldefault.c (struct _GtkFileChooserImplDefault):
Added an extra_widget field.
(gtk_file_chooser_impl_default_set_property): Handle the
"extra-widget" property.
(gtk_file_chooser_impl_default_get_property): Likewise.
(set_preview_widget): Fix the call gtk_container_remove(). Also,
we don't need to ref/sink/unref the preview widget, as that gets
already done by container_add/remove.
(set_extra_widget): New utility function.
* testfilechooser.c (main): Add an extra widget.
