This can be used to fetch the serial number of the peer certificate in
the EAP server. For now, this is implemented only with OpenSSL.

The n argument to this function is number of bits, not bytes, to shift.
As such, need to use mp_rshb() instead of mp_rshd(). This fixes EAP-pwd

This may be needed to avoid interoperability issues with the new

derivation and handshake termination.

This makes this more easily available throughout the handshake
processing, if needed, compared to having to pass through the function
argument through the full path from
tls_connection{,_server}_handshake().

OpenSSL 1.1.1 added cases where ClientHello generation may fail due to
"no ciphers available". There is no point in sending out the resulting
TLS Alert message to the server since the server does not know what to
do with it before ClientHello. Instead, simply terminate the TLS
handshake locally and report EAP failure to avoid getting stuck waiting
for a timeout.

LibreSSL v2.7 claims an OPENSSL_VERSION_NUMBER value that would indicate
that SSL_OP_NO_TLSv1_3 is available, but that does not seem to be the
case with LibreSSL. As such, skip this step based on whether
SSL_OP_NO_TLSv1_3 is defined to avoid build issues.

BoringSSL removed the special OpenSSL cipher suite value "SUITEB192", so
need to map that to the explicit ciphersuite
(ECDHE-ECDSA-AES256-GCM-SHA384), curve (P-384), and sigalg
(SSL_SIGN_ECDSA_SECP384R1_SHA384) to allow 192-bit level Suite B with
ECDSA to be used.

In practice, this does the same thing (i.e., allows only the P-384 curve
to be used), but using an older API function that happens to be
available in some BoringSSL builds while the newer one is not.

TLS v1.3 needs to be explicitly disabled to allow cipher suite selection
for EAP-FAST to work with OpenSSL builds that include TLS v1.3 support.
Without this, OpenSSL refuses to generate ClientHello due to the cipher
suite list including only ciphers allowed with older versions than TLS
v1.3.
