c24e18e5c5 LibreSSL: Fix compilation issue with TLS 1.3 session ticket limit
LibreSSL does not seem have SSL_CTX_set_num_tickets(), so comment out
these not really critical calls when building with that library.

a561d12d24 EAP peer status notification for server not supporting RFC 5746
Add a notification message to indicate reason for TLS handshake failure

566ce69a8d EAP peer: Workaround for servers that do not support safe TLS renegotiation
The TLS protocol design for renegotiation was identified to have a
significant security flaw in 2009 and an extension to secure this design
was published in 2010 (RFC 5746). However, some old RADIUS
authentication servers without support for this are still used commonly.

This is obviously not good from the security view point, but since there
are cases where the user of a network service has no realistic means for
getting the authentication server upgraded, TLS handshake may still need
to be allowed to be able to use the network.

OpenSSL 3.0 disabled the client side workaround by default and this
resulted in issues connection to some networks with insecure
authentication servers. With OpenSSL 3.0, the client is now enforcing
security by refusing to authenticate with such servers. The pre-3.0
behavior of ignoring this issue and leaving security to the server can
now be enabled with a new phase1 parameter allow_unsafe_renegotiation=1.
This should be used only when having to connect to a network that has an
insecure authentication server that cannot be upgraded.

The old (pre-2010) TLS renegotiation mechanism might open security
vulnerabilities if the authentication server were to allow TLS
renegotiation to be initiated. While this is unlikely to cause real
issues with EAP-TLS, there might be cases where use of PEAP or TTLS with
an authentication server that does not support RFC 5746 might result in
a security vulnerability.

10746875e2 OpenSSL: Allow no OCSP response when resuming a session with TLS 1.3
TLS 1.3 sends the OCSP response with the server Certificate message.
Since that Certificate message is not sent when resuming a session,
there can be no new OCSP response. Allow this since the OCSP response

f5c711c855 OpenSSL: Unload providers only at process exit
The previous mechanism of unloaded the providers from tls_deinit() did
not work correctly for some cases. In particular, it was possible for
hostapd to end up unloading both providers and not being able to recover

Address this more cleanly by introducing a new crypto_unload() function
that will be called when the process is exiting.
