	Improved DND support for GtkNotebook  (#332991, Carlos Garnacho)

	* gtk/gtk.symbols:
	* gtk/gtkdnd.h:
	* gtk/gtkdnd.c: Add a track_motion flag on GtkDragDest
	with getter and setter, for cases where the drag destination
	is interested in drag motion events independent of targets.

	* gtk/gtksettings.c (gtk_settings_class_init): Add a setting
	for the timeout used when expanding during DND.

	* gtk/gtknotebook.c: Use the track_motion flag to switch
	notebook tabs when hovering over tabs during DND.
