force failed header parse to act

''...Websocket servers return failure responses other than HTTP Status 101 in the case of
mismatches of WebSocket version or additional header data etc...
It seems that libwebsockets shows "WARN: problems parsing header" error in such cases without
calling any callbacks or returning error code. Is this right?
I modified lib/client.c to handle this.''
