HTTP/3: require mandatory uni streams before additional ones. As per quic-http-34: Endpoints SHOULD create the HTTP control stream as well as the unidirectional streams required by mandatory extensions (such as the QPACK encoder and decoder streams) first, and then create additional streams as allowed by their peer. Previously, client could create and destroy additional uni streams unlimited number of times before creating mandatory streams.
