nginx-quic: src/event/ngx_event

annotate src/event/ngx_event_quic.h @ 7862:fb7422074258 quic

Added generation of CC frames with error on connection termination. When an error occurs, then c->quic->error field may be populated with an appropriate error code, and the CONNECTION CLOSE frame will be sent to the peer before the connection is closed. Otherwise, the error treated as internal and INTERNAL_ERROR code is sent. The pkt->error field is populated by functions processing packets to indicate an error when it does not fit into pass/fail return status.
