nginx: src/event/ngx_event

annotate src/event/ngx_event_quic.c @ 8397:1245e274b9ba quic

Avoided excessive definitions for connection state. There is no need in a separate type for the QUIC connection state. The only state not found in the SSL library is NGX_QUIC_ST_UNAVAILABLE, which is actually a flag used by the ngx_quic_close_quic() function to prevent cleanup of uninitialized connection.
