annotate src/event/quic/ngx_event_quic_connid.c @ 9192:efcdaa66df2e

QUIC: congestion control in ngx_quic_frame_sendto(). Previously ngx_quic_frame_sendto() ignored congestion control and did not contribute to in_flight counter. Now congestion control window is checked unless ignore_congestion flag is set. Also, in_flight counter is incremented and the frame is stored in ctx->sent queue if it's ack-eliciting. This behavior is now similar to ngx_quic_output_packet().
