QUIC: idle mode for main connection. Now main QUIC connection for HTTP/3 always has c->idle flag set. This allows the connection to receive worker shutdown notification. It is passed to application level via a new conf->shutdown() callback. The HTTP/3 shutdown callback sends GOAWAY to client and gracefully shuts down the QUIC connection.
