Only ECDHE-based ciphers are implemented. To ease the transition, the
pre-standard cipher shares a name with the standard one. The cipher rule parser
is hacked up to match the name to both ciphers. From the perspective of the
cipher suite configuration language, there is only one cipher.
This does mean it is impossible to disable the old variant without a code
change, but this situation will be very short-lived, so this is fine.
Also take this opportunity to make the CK and TXT names align with convention.

The internal session cache is keyed on session ID, so this is completely
useless for clients (indeed we never look it up internally). Along the way,
tidy up ssl_update_cache to be more readable. The slight behavior change is
that SSL_CTX_add_session's return code no longer controls the external
callback. It's not clear to me what that could have accomplished. (It can only
fail on allocation error. We only call it for new sessions, so the duplicate
case is impossible.)
The one thing of value the internal cache might have provided is managing the
timeout. The SSL_CTX_flush_sessions logic would flip the not_resumable bit and
cause us not to offer expired sessions (modulo SSL_CTX_flush_sessions's delay
and any discrepancies between the two caches). Instead, just check expiration
when deciding whether or not to offer a session.
This way clients that set SSL_SESS_CACHE_CLIENT blindly don't accidentally
consume gobs of memory.

SSL_get_client_CA_list is one of those dreaded functions which may query either
configuration state or handshake state. Moreover, it does so based on
|ssl->server|, which may not be configured until later. Also check
|ssl->handshake_func| to make sure |ssl| is not in an indeterminate state.
This also fixes a bug where SSL_get_client_CA_list wouldn't work in DTLS due to
the incorrect |ssl->version| check.

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.

that the top-level object won't be overridden.

Rather than shoehorn real ciphers and cipher aliases into the same type (that's
what cipher->valid is used for), treat them separately. Make
ssl_cipher_apply_rule match ciphers by cipher_id (the parameter was ignored and
we assumed that masks uniquely identify a cipher) and remove the special cases
around zero for all the masks. This requires us to remember which fields
default to 0 and which default to ~0u, but the logic is much clearer.
Finally, now that ciphers and cipher aliases are different, don't process rules
which sum together an actual cipher with cipher aliases. This would AND
together the masks for the alias with the values in the cipher and do something
weird around alg_ssl. (alg_ssl is just weird in general, as everyone trying to
disable SSLv3 in OpenSSL recently discovered.)
With all that, we can finally remove cipher->valid which was always one.
