* QUIC integration.
*
* QUIC acts as an underlying transport for the TLS 1.3 handshake. The following
* functions allow a QUIC implementation to serve as the underlying transport as
* described in RFC 9001.
*
* When configured for QUIC, |SSL_do_handshake| will drive the handshake as
* before, but it will not use the configured |BIO|. It will call functions on
* |SSL_QUIC_METHOD| to configure secrets and send data. If data is needed from
* the peer, it will return |SSL_ERROR_WANT_READ|. As the caller receives data
* it can decrypt, it calls |SSL_provide_quic_data|. Subsequent
* |SSL_do_handshake| calls will then consume that data and progress the
* handshake. After the handshake is complete, the caller should continue to
* call |SSL_provide_quic_data| for any post-handshake data, followed by
* |SSL_process_quic_post_handshake| to process it. It is an error to call
* |SSL_peek|, |SSL_read| and |SSL_write| in QUIC.
*
* To avoid DoS attacks, the QUIC implementation must limit the amount of data
* being queued up. The implementation can call
* |SSL_quic_max_handshake_flight_len| to get the maximum buffer length at each
* encryption level.
*
* QUIC implementations must additionally configure transport parameters with
* |SSL_set_quic_transport_params|. |SSL_get_peer_quic_transport_params| may be
* used to query the value received from the peer. This extension is handled
* as an opaque byte string, which the caller is responsible for serializing
* and parsing. See RFC 9000 section 7.4 for further details.
