QUIC: coalesce neighbouring stream send buffers. Previously a single STREAM frame was created for each buffer in stream output chain which is wasteful with respect to memory. The following changes were made in the stream send code: - ngx_quic_stream_send_chain() no longer calls ngx_quic_stream_send() and got a separate implementation that coalesces neighbouring buffers into a single frame - the new ngx_quic_stream_send_chain() respects the limit argument, which fixes sendfile_max_chunk and limit_rate - ngx_quic_stream_send() is reimplemented to call ngx_quic_stream_send_chain() - stream frame size limit is moved out to a separate function ngx_quic_max_stream_frame() - flow control is moved out to a separate function ngx_quic_max_stream_flow() - ngx_quic_stream_send_chain() is relocated next to ngx_quic_stream_send()
