      Description

      When http_proxy is set to "http://someproxy", and the application calls QNetworkProxyFactory::setUseSystemConfiguration(true), QTcpServer::bind() fails.

      QNativeSocketEnginePrivate::checkProxy fails since server->proxy() is QNetworkProxy::DefaultProxy, and QNetworkProxy::applicationProxy() returns a proxy for QNetworkProxyQuery::TcpSocket and not TcpServer.

      I think there is no need to check the proxy for QTcpServer, since QTcpServer::listen calls QAbstractSocketEngine::createSocketEngine, which only creates a QNativeSocketEngine when the resolved proxy is QNetworkProxy::NoProxy.
