Move cert_chain to the SSL_SESSION. Now everything on an SSL_SESSION is
properly serialized. The cert_chain field is, unfortunately, messed up
since it means different things between client and server.
There exists code which calls SSL_get_peer_cert_chain as both client and
server and assumes the existing semantics for each. Since that function
doesn't return a newly-allocated STACK_OF(X509), normalizing between the
two formats is a nuisance (we'd either need to store both cert_chain and
cert_chain_full on the SSL_SESSION or create one of the two variants
on-demand and stash it into the SSL).
This CL does not resolve this and retains the client/server difference
in SSL_SESSION. The SSL_SESSION serialization is a little inefficient
(two copies of the leaf certificate) for a client, but clients don't
typically serialize sessions. Should we wish to resolve it in the
future, we can use a different tag number. Because this was historically
unserialized, existing code must already allow for cert_chain not being
preserved across i2d/d2i.
In keeping with the semantics of retain_only_sha256_of_client_certs,
cert_chain is not retained when that flag is set.

Rather than write a dup function, serializing and deserializing the object is
simpler. It also fixes a bug in the original fix where it never calls
new_session_cb to store the new session (for clients which use that callback;
how clients should handle the session cache is much less clear).
The old session isn't pruned as we haven't processed the Finished message yet.
RFC 5077 says:
The server MUST NOT assume that the client actually received the updated
ticket until it successfully verifies the client's Finished message.
Moreover, because network messages are asynchronous, a new SSL connection may
have began just before the client received the new ticket, so any such servers
are broken regardless.

Note that this changes the object reuse story slightly. It's now merely an
optional output pointer that frees its old contents. No d2i_SSL_SESSION
consumer in Google that's built does reuse, much less reuse with the assumption
that the top-level object won't be overridden.

As of our 82b7da271f, an SSL_SESSION created
externally always has a cipher set. Unknown ciphers are rejected early. Prior
to that, an SSL_SESSION would only have a valid cipher or valid cipher_id
depending on whether it came from an internal or external session cache.
See upstream's 6a8afe2201cd888e472e44225d3c9ca5fae1ca62 and
c566205319beeaa196e247400c7eb0c16388372b for more context.
Since we don't get ourselves into this strange situation and s->cipher is now
always valid for established SSL_SESSION objects (the existence of
unestablished SSL_SESSION objects during a handshake is awkward, but something
to deal with later), do away with s->cipher_id altogether. An application
should be able to handle failing to parse an SSL_SESSION instead of parsing it
successfuly but rejecting all resumptions.

There's not much point in retaining the identity hint in the SSL_SESSION. This
avoids the complexity around setting psk_identity hint on either the SSL or the
SSL_SESSION. Introduce a peer_psk_identity_hint for the client to store the one
received from the server.
This changes the semantics of SSL_get_psk_identity_hint; it now only returns
the value configured for the server. The client learns the hint through the
callback. This is compatible with the one use of this API in conscrypt (it
pulls the hint back out to pass to a callback).

Doing some archeaology, since the initial OpenSSL commit, key_arg has been
omitted from the serialization if key_arg_length was 0. Since this is an
SSLv2-only field and resuming an SSLv2 session with SSLv3+ is not possible,
there is no need to support parsing those sessions.
Interestingly, it is actually not the case that key_arg_length was only ever
set in SSLv2, historically. In the initial commit of OpenSSL, SSLeay 0.8.1b,
key_arg was used to store what appears to be the IV. That was then removed in
the next commit, an import of SSLeay 0.9.0b, at which point key_arg was only
ever set in SSLv3. That is old enough that there is certainly no need to
parse pre-SSLeay-0.9.0b sessions...
