As of our 82b7da271ff13a2878e921f0d262812d111a7b84, 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 6a8afe2201 and
c566205319 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.

This avoids needing a should_add_to_finished_hash boolean on do_write. The
logic in do_write was a little awkward because do_write would be called
multiple times if the write took several iterations. This also gets complex if
DTLS retransmits are involved. (At a glance, it's not obvious the
BIO_CTRL_DGRAM_MTU_EXCEEDED case actually works.)
Doing it as the handshake message is being prepared avoids this concern. It
also gives a natural point for the extended master secret logic which needs to
do work after the finished hash has been sampled.

Which is fortunate because it'll trigger SSL_clear. This retains the BIOs but

When not offering to resume a session, the client populates s->session with a
fresh SSL_SESSION before the ServerHello is processed and, in DTLS_ANY_VERSION,
before the version is even determined. Don't create a fresh SSL_SESSION until
we know we are doing a full handshake.
This brings ssl3_send_client_hello closer to ssl23_client_hello in behavior. It
also fixes ssl_version in the client in DTLS_ANY_VERSION.
SSLv23_client_method is largely unchanged. If no session is offered, s->session
continues to be NULL until the ServerHello is received. The one difference is
that s->session isn't populated until the entire ServerHello is received,
rather than just the first half, in the case of a fragmented ServerHello. Apart
from info_callback, no external hooks get called between those points, so this
shouldn't expose new missing NULL checks.
The other client methods change significantly to match SSLv23_client_method's

SSLv23_client_method (and version-specific methods are already weird), so that
should be safe. For DTLS, I've verified that accesses in d1_*.c either handle
NULL or are after the ServerHello.

The current implementation switches the order of other_secret and psk;
other_secret is first. Fix it and rewrite with CBB instead. The server half got
fixed on accident in a prior refactor.

Remove one more difference to worry about switching between TLS and SSLv3
method tables.
Although this does change the get_ssl_method hook for the version-specific
tables (before TLS and SSLv3 would be somewhat partitioned), it does not appear
to do anything. get_ssl_method is only ever called in SSL_set_session for
client session resumption. Either you're using the version-specific method
tables and don't know about other versions anyway or you're using SSLv23 and
don't partition TLS vs SSL3 anyway.

The TLS-specific hooks have been removed. We aim to no longer perform version
negotiation as a pre-processing step, so ensure the only differences to worry
about are the version, get_method hook, and the enc_data.
