Tidy nullptr usage
Move away from using 0 as pointer literal. Done using clang-tidy. This is not complete as run-clang-tidy can't handle all of qtbase in one go. Change-Id: I1076a21f32aac0dab078af6f175f7508145eece0 Reviewed-by: Friedemann Kleint <Friedemann.Kleint@qt.io> Reviewed-by: Lars Knoll <lars.knoll@qt.io>
