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.

Note that this changes the object reuse story slightly. It's now merely an

consumer in Google that's built does reuse, much less reuse with the assumption
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.

Also change some incorrect flags on SHA-256 TLS 1.2 ciphers;
SSL_HANDSHAKE_MAC_DEFAULT and SSL_HANDSHAKE_MAC_SHA256 are the same after TLS
1.2. A TLS 1.2 cipher should be tagged explicitly with SHA-256. (This avoids
tripping a check in SSL_CIPHER_get_rfc_name which asserts that default-hash
ciphers only ever use SHA-1 or MD5 for the bulk cipher MAC.)

As a bonus, we can now handle fragmented ClientHello versions now.

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

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...
