        WebSocket handshake incompatible change in draft-hixie-thewebsocketprotocol-76
        https://bugs.webkit.org/show_bug.cgi?id=35572

        Fix LayoutTests for new WebSocket protocol.
        It requires https://bugs.webkit.org/show_bug.cgi?id=38034 to pass websocket tests.

        * websocket/tests/handshake-error-expected.txt: Update expected data.
        * websocket/tests/handshake-error_wsh.py: Without CRLF, the wsh will sends "ThisWillCauseHandshakeErrorHTTP/1.1 101 WebSocket Protocol Handshake\r\n", which is legal for the first line of draft 76 WebSocket opening handshake. (4.1 Opening Handhshake, step 28 to 30).  To fail handshake, it needs \r\n.
        * websocket/tests/long-invalid-header-expected.txt:  Originally, it expects Upgrade header after status line.  In draft 76, order is not important.  But "pppp..\r\n" would fail because it misses ":" (end of name) before \r.
