annotate src/event/ngx_event_quic.c @ 8328:e76be8639621 quic

Added basic offset support in client CRYPTO frames. The offset in client CRYPTO frames is tracked in c->quic->crypto_offset_in. This means that CRYPTO frames with non-zero offset are now accepted making possible to finish handshake with client certificates that exceed max packet size (if no reordering happens). The c->quic->crypto_offset field is renamed to crypto_offset_out to avoid confusion with tracking of incoming CRYPTO stream.
