count down from G_MAXUINT to avoid clashes with application-added DND

	* gtk/gtktextbuffer.h (enum GtkTextBufferTargetInfo): count down
	from G_MAXUINT to avoid clashes with application-added DND
	targets.

	* gtk/gtktextview.c (gtk_text_view_init): set an empty
	GtkTargetList on the drag_dest so it is not NULL when a derived
	class' init() function is called.

	(gtk_text_view_target_list_notify): copy the text buffer's paste
	targets into the view's destinstion target list (preserving
	application-added DND targets), instead of replacing the view's
	target list. Fixes bug #334399.
