-2 is really weird. On sign, it's maximal length. On verify, it actually
accepts all lengths. This sounds somewhat questionable to me, but just
document the state of the world for now. Also add a recommendation to
use -1 (match digest length) to align with TLS 1.3, tokbind, and QUIC
Crypto. Hopefully the first two is sufficient that the IETF will forever
use this option and stop the proliferation of RSA-PSS parameters.

The tests are a little odd because OpenSSL supports this "salt length

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.

but will be written in a way incompatible with older versions of the

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.
