Bug 607628 - DnD operation doesn't work when using offscreen

Turn find_widget_under_pointer() into internal API
_gtk_widget_find_at_coords() which is needed for fixing above
bug. This should actually be a public utility function, and will be
moved to another file when its final API has been decided.
