By integrating the use of long path prefix (\?\\) and careful use of short paths we can workaround most of the MSI API long path limitations. It's not perfect as short paths that still exceed MAX_PATH will fail in most MSI APIs. But accessing files placed in cabinets and copied around should now be fully long path supported. Fixes 3065 9115
