py3: provide bytes stdin/out/err through util module Since standard streams are TextIO on Python 3, we can't use sys.stdin/out/err directly. Fortunately we can get the underlying BytesIO via .buffer as long as the streams aren't replaced by e.g. StringIO. stdin/out/err are provided through util so we can wrap them by platform API.
