QNAM HTTP: Introduce attributes for controlling cookies and auth

Introduced QNetworkRequest::CookieLoadControlAttribute,
QNetworkRequest::CookieSaveControlAttribute and
QNetworkRequest::AuthenticationReuseControlAttribute

These are true by default. They only come into play when QtWebKit
processes a cross-origin XMLHttpRequest. In such cases QtWebKit sets
each of the attributes to false when it creates a QNetworkRequest
where the XMLHttpRequest is cross-origin and has withCredentials
set to false:

var req = new XMLHttpRequest;
req.open("GET", "http://host/resource.php", false);
req.withCredentials = false; // actually false by default

For more information:

The QtWebKit counterpart of this patch is tracked at:
   https://bugs.webkit.org/show_bug.cgi?id=32967
