HTTP/2: send WINDOW_UPDATE instead of RST_STREAM with NO_ERROR. After the 92464ebace8e change, it has been discovered that not all clients follow the RFC and handle RST_STREAM with NO_ERROR properly. Notably, Chrome currently interprets it as INTERNAL_ERROR and discards the response. As a workaround, instead of RST_STREAM the maximum stream window update will be sent, which will let client to send up to 2 GB of a request body data before getting stuck on flow control. All the received data will be silently discarded. See for details: http://mailman.nginx.org/pipermail/nginx-devel/2016-April/008143.html https://bugs.chromium.org/p/chromium/issues/detail?id=603182
