QUIC: stream lingering. Now ngx_quic_stream_t is decoupled from ngx_connection_t in a way that it can persist after connection is closed by application. During this period, server is expecting stream final size from client for correct flow control. Also, buffered output is sent to client as more flow control credit is granted.
