There are no longer any consumers of these APIs.
These were useful back when the CBC vs. RC4 tradeoff varied by version
and it was worth carefully tuning this cutoff. Nowadays RC4 is
completely gone and there's no use in configuring these anymore.
To avoid invalidating the existing ssl_ctx_api corpus and requiring it
regenerated, I've left the entries in there. It's probably reasonable
for new API fuzzers to reuse those slots.

OpenSSL includes a leaf certificate in a certificate chain when it's a
client, but doesn't when it's a server. This is also reflected in the
serialisation of sessions.
This change makes the internal semantics consistent: the leaf is always
included in the chain in memory, and never duplicated when serialised.
To maintain the same API, SSL_get_peer_cert_chain will construct a copy
of the chain without the leaf if needed.
Since the serialised format of a client session has changed, an
|is_server| boolean is added to the ASN.1 that defaults to true. Thus
any old client sessions will be parsed as server sessions and (silently)
discarded by a client.

This is to free up moving ssl->state into SSL_HANDSHAKE. ssl->state
serves two purposes right now. First, it is the state tracking for
SSL_HANDSHAKE. Second, it lets the system know there is a handshake
waiting to complete.
Instead, arrange things so that, if there is a handshake waiting to
complete, hs is not NULL. That means we need to initialize it when
creating a new connection and when discovering a renego.
Note this means we cannot make initializing an SSL_HANDSHAKE depend on
client vs. server.

The serialisation format of SSL_SESSIONs is also changed, in a backwards
compatible way. Previously, some sessions would duplicate the leaf
certificate in the certificate chain. These sessions can still be read,
but will be written in a way incompatible with older versions of the
code. This should be fine because the situation where multiple versions
exchange serialised sessions is at the server, and the server doesn't
duplicate the leaf certifiate in the chain anyway.

Right now the only way to set an OCSP response is SSL_CTX_set_ocsp_response
however this assumes that all the SSLs generated from a SSL_CTX share the
same OCSP response, which is wrong.
This is similar to the OpenSSL "function" SSL_get_tlsext_status_ocsp_resp,
the main difference being that this doesn't take ownership of the OCSP buffer.
In order to avoid memory duplication in case SSL_CTX has its own response,
a CRYPTO_BUFFER is used for both SSL_CTX and SSL.

wpa_supplicant relies on this behavior, so restore it for TLS 1.2 and
