annotate src/event/ngx_event_quic_transport.c @ 8596:38c7dd720774 quic

QUIC: added ACK frame range support. The history of acknowledged packet is kept in send context as ranges. Up to NGX_QUIC_MAX_RANGES ranges is stored. As a result, instead of separate ack frames, single frame with ranges is sent.
