Asynchronously creates a classWebsocketConnection to communicate with a
remote server.
All necessary WebSocket-related headers will be added to msg, and
it will then be sent and asynchronously processed normally
(including handling of redirection and HTTP authentication).
If the server returns "101 Switching Protocols", then msg's status
code and response headers will be updated, and then the WebSocket
handshake will be completed. On success,
soup.session.Session.websocketConnectFinish will return a new
classWebsocketConnection. On failure it will return a #GError.
