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()
