RFR [9] 8180155: WebSocket secure connection get stuck after onOpen

[Pavel Rappo]

Hello,

Please review the following change:

 http://cr.openjdk.java.net/~prappo/8180155/webrev.00/

This change addresses 2 separate issues:

    https://bugs.openjdk.java.net/browse/JDK-8180155
    https://bugs.openjdk.java.net/browse/JDK-8156518

The first one is a busy-wait for data on the socket which manifests itself as
non-returning invocation of WebSocket.request(long).

The second one is an issue with a timeout for an asynchronous HTTP request.
This issue affects both HttpClient and WebSocket implementations.

Thanks,
-Pavel
