annotate src/event/ngx_event_quic.c @ 8308:e10b4c61420f quic

Implemented retransmission and retransmit queue. All frames collected to packet are moved into a per-namespace send queue. QUIC connection has a timer which fires on the closest max_ack_delay time. The frame is deleted from the queue when a corresponding packet is acknowledged. The NGX_QUIC_MAX_RETRANSMISSION is a timeout that defines maximum length of retransmission of a frame.
