6882609: Move default InMemoryCookieStore to java.net
Webrev: http://cr.openjdk.java.net/~chegar/6882609/webrev.0/webrev/The default cookie store implementation (InMemoryCookieStore) currently resides in sun.net.www.protocol.http. There is no reason for it to live there, and it actually puts a static dependency on sun.net from java.net
Thanks, -Chris.
