QUIC: stream flow control refactored. - Function ngx_quic_control_flow() is introduced. This functions does both MAX_DATA and MAX_STREAM_DATA flow controls. The function is called from STREAM and RESET_STREAM frame handlers. Previously, flow control was only accounted for STREAM. Also, MAX_DATA flow control was not accounted at all. - Function ngx_quic_update_flow() is introduced. This function advances flow control windows and sends MAX_DATA/MAX_STREAM_DATA. The function is called from RESET_STREAM frame handler, stream cleanup handler and stream recv() handler.
