Request for Review 6882594

Hi Jessie, Michael, Alan,

6882594: Remove static dependency on NTLM authentication
Webrev:
  http://cr.openjdk.java.net/~chegar/6882594/webrev.0

The HTTP client implementation 
(sun.net.www.protocol.http.HttpURLConnection) loads the NTLM 
Authentication classes even if no authentication is used. These classes 
should not be loaded unless required. Also, make NTLM a runtime 
dependency rather than a static one.

I took the liberty of cleaning up some imports along the way.

-Chris.
