define __GTK_H_INSIDE__ around including all other headers.

2008-05-28  Michael Natterer  <mitch@imendio.com>

	* gtk/gtk.h: define __GTK_H_INSIDE__ around including all other
	headers.

	* gtk/gtktypebuiltins.h.template
	* gtk/gtkversion.h.in
	* gtk/gtk*.h: add single-include guards that #error out if
	GTK_DISABLE_SINGLE_INCLUDES is defined and any of these files is
	included individually.

	* gtk/gtkprintbackend.h
	* gtk/gtkprinter-private.h
	* gtk/gtktextlayout.h
	* gtk/gtktexttagprivate.h
	* gtk/gtktexttypes.h
	* gtk/gtktreedatalist.h: include <gtk/gtk.h> instead of individual
	headers in these private or semi-private headers.

	* gtk/gtkimmodule.h: also here because it's not in gtk.h.

	* gtk/gtkpagesetupunixdialog.h
	* gtk/gtkprinter.h
	* gtk/gtkprintjob.h
	* gtk/gtkprintunixdialog.h: likewise in the gtkunixprint headers.

	* gtk/gtkclist.h
	* gtk/gtkcombo.h
	* gtk/gtkctree.h
	* gtk/gtkfilesel.h
	* gtk/gtkitemfactory.h
	* gtk/gtklist.h
	* gtk/gtklistitem.h
	* gtk/gtkoldeditable.h
	* gtk/gtkoptionmenu.h
	* gtk/gtkpixmap.h
	* gtk/gtkpreview.h
	* gtk/gtksignal.h
	* gtk/gtktipsquery.h: whenever possible, include only <gtk/gtk.h>
	instead of individual headers in these deprecated headers. They
	don't get included at all when GTK_DISABLE_DEPRECATED is defined,
	so if an app needs them anyway, it must undef GTK_DISABLE_DEPRECATED
	and include them individually, which should continue to work.

	* gtk/gtkclist.c: include "gtkctree.h" because of the change
	above.
