1. fix the test for HTTP protocol upgrade …

   If the HTTP client wants to request protocol upgrade, it must
   send the `Upgrade` header. It should also set the `Connection`
   header. This test didn't do that, so conforming implementations
   could reject the `request.upgrade()` call. The fix is simple:
   add the 2 headers on the client side (i.e., in the test).
   
   To be able to set `Connection` and `Upgrade` headers on the
   `java.net.HttpURLConnection`, restricted headers must be allowed
   by setting a special system property.
   
   See also https://developer.mozilla.org/en-US/docs/Web/HTTP/Protocol_upgrade_mechanism
   and the Servlet specification 4.0, section 2.3.3.5.
