This is the only thing I don't like about this change.

Because WebCore doesn't have access to src/net/base/net_errors.h, it doesn't
know the chromium net error codes. So I don't see how to make this otherwise
reasonable change without duplicating the cancellation error code definition.

+{
+    ResourceError error(errorDomainNet, cancelledErrorCode, failingURL, String());
+    error.setIsCancellation(true);
+    return error;
+}

+ResourceError ResourceError::createPolicyChangeError(const String& failingURL)

+    return ResourceError(errorDomainWebKitInternal, policyChangeError, failingURL, String());

     ResourceError errorCopy;
