	* tests/autotestfilechooser.c: Start a set of automated tests for
	the file chooser.  The only test in there right now doesn't pass
	yet.  It specifies the intended behavior of the first optimization
	of a series which I'll do on the file chooser (see
	http://primates.ximian.com/~federico/news-2005-09.html#14 for the
	details of this optimization).

	* tests/Makefile.am: Added autotestfilechooser.c.

	* gtk/gtkfilechooserprivate.h (struct
	_GtkFileChooserDialogPrivate): Move all the file chooser's private
	structures to here, so that they can be accessed by
	tests/autotestfilechooser.c:  _GtkFileChooserDialogPrivate,
	_GtkFileChooserWidgetPrivate, LoadState, _GtkFileChooserDefault.

	* gtk/gtkfilechooserdialog.c: See above.

	* gtk/gtkfilechooserwidget.c: See above.

	* gtk/gtkfilechooserdefault.c: See above.
