It's easy to forget to check those. Unfortunately, it's also easy to
forget to check inner structures, which is going to be harder to stress,
but do these to start with. In doing, so fix up and unify some
error-handling, and add a missing check when parsing TLS 1.2
CertificateRequest.
This was also inspired by the recent IETF posting.

This allows us to switch TLS 1.3 to use non-cipher based negotiation
without needing to use separate functions between 1.3 and below.

tls13_process_certificate can take a boolean for whether anonymous is
allowed. This does change the error on the client slightly, but I think
this is correct anyway. It is not a syntax error for the server to send
no certificates in so far as the Certificate message allows it. It's
just illegal.

We will now send tickets as a server and accept them as a
client. Correctly offering and resuming them in the handshake will be
implemented in a follow-up.
Now that we're actually processing draft 14 tickets, bump the draft
version.

In TLS 1.2, this was allowed to be empty for the weird SHA-1 fallback
logic. In TLS 1.3, not only is the fallback logic gone, but omitting
them is a syntactic error.

To prevent configuration/established session confusion, the handshake
session state is separated into the configured session (ssl->session)
and the newly created session (ssl->s3->new_session). Upon conclusion of
the handshake, the finalized session is stored
in (ssl->s3->established_session). During the handshake, any requests
for the session (SSL_get_session) return a non-resumable session, to
prevent resumption of a partially filled session. Sessions should only
be cached upon the completion of the full handshake, using the resulting
established_session. The semantics of accessors on the session are
maintained mid-renego.

This doesn't do anything since they're for DTLS, but we ought to satisfy
the API nonetheless. expect_flight is easy with
ssl_hs_flush_and_read_message. received_flight I think basically needs
to get sprinkled into the state machine.
