RFR(s): 8228580: DnsClient TCP socket timeout

[Pavel Rappo]

I'm happy with the overall changeset. I have (once again) made some tiny changes, you can see them here:

    http://cr.openjdk.java.net/~prappo/8228580/webrev.02/    

If you are okay with them, then we wait for a *R*eviewer. If the Reviewer(s) are okay with them, we push. For the record, I'm not really happy with how we used the DNSTestBase/TestBase infrastructure, however I'm totally fine with the retrying logic.

Test results are pending.
