[gtk+] dnd: Cleanups

[Matthias Clasen <matthiasc src gnome org>]

commit a22c1ec9807d11118c3f822feb0429fa38ba9cf6
Author: Matthias Clasen <mclasen redhat com>

    dnd: Cleanups
    
    Remove some now unused includes and dead code, and rename
    gtk_drag_set_icon_window to gtk_drag_set_icon_widget_internal,
    since it is no longer restricted to toplevel windows.
