Code Review 6632169: HttpClient and HttpsClient should not try to reverse lookup IP address of a proxy server

[Christopher Hegarty - Sun Microsystems Ireland]

Hi Michael,

This is a forward port of a fix from JDK6u6 to JDK7. The source changes 
are small and the very same as what went in 6.

The HttpClient was changed to use getHostString (does not perform 
reverse lookup), but the HttpsClient was overlooked at the time. This 
fix changes the HttpsClient to delegate to the already fixed HttpClient.
