annotate src/event/ngx_event_quic.c @ 8263:1295b293d09a quic

Connection states code cleanup. + ngx_quic_init_ssl_methods() is no longer there, we setup methods on SSL connection directly. + the handshake_handler is actually a generic quic input handler + updated c->log->action and debug to reflect changes and be more informative + c->quic is always set in ngx_quic_input() + the quic connection state is set by the results of SSL_do_handshake();
