	* gtk/gtkmarshal.list: add new marshallers used by the text widget

	* gtk/gtktextbuffer.c (gtk_text_buffer_class_init): fix marshaller
	types

	* gtk/gtktexttagtable.c (gtk_text_tag_table_class_init): fix
	marshaller types

	* gtk/gtktextlayout.h, gtk/gtktextlayout.c, gtk/gtktextdisplay.h,
	gtk/gtktextdisplay.c: We need to preserve Tk copyrights and
	license on these files.

	* gtk/gtktextiter.c (gtk_text_iter_backward_search): Make this
	work.

	* gtk/gtktextbtree.c (gtk_text_btree_new): init stamps to
	runtime random number different for each tree, instead of
	a constant I made up.
