annotate src/event/ngx_event_quic.c @ 8477:031918df51c0 quic

QUIC: added anti-amplification limit. According to quic-transport draft 29, section 21.12.1.1: Prior to validation, endpoints are limited in what they are able to send. During the handshake, a server cannot send more than three times the data it receives; clients that initiate new connections or migrate to a new network path are limited.
