This is the first of reorganizing state between connection state and handshake
state. The existing set are retained in cert_st for the server; they are server
configuration. The client gets a copy in s->s3->tmp alongside other handshake
state.
With other handshake state moved there, hopefully we can reset that state in
one go and possibly not even maintain it when there is no handshake in
progress. Rather than currently where we sometimes confused connection state
and handshake state and have to reset as appropriate on renegotiate.
While I'm here, document the fields and name them something more useful than
'ctypes'.

Along the way, clean up the certificate types code to not have the
hard-coded fixed-size array.

Found no users of the functions which control the feature. (Also I don't
particularly want to port all of that to CBS...)

This code doesn't even get built unless you go out of your way to pass an

This gives us systematic bounds-checking on all the parses. Also adds a
convenience function, CBS_memdup, for saving the current contents of a CBS.

OpenSSL added SSL_get0_certificate_types and fixed the truncation (and
subsequent parse error) by adding an alternate copy of the data.

Make SSL_get_client_certificate_types call SSL_get0_certificate_types to query
the new list. Remove when Chromium is switched over.
Also remove a now unnecessary cast because SSL_get_client_certificate_types
fixed the type of tmp.ctypes. Further fix it to use a size_t and match the
cert_st copy OpenSSL added.

Only accept change cipher spec when it is expected instead of at any
time. This prevents premature setting of session keys before the master
secret is determined which an attacker could use as a MITM attack.
Thanks to KIKUCHI Masashi (Lepidum Co. Ltd.) for reporting this issue
and providing the initial fix this patch is based on.
(Imported from upstream's 77719aefb8f549ccc7f04222174889615d62057b)
This patch removes support for empty records (which is almost
universally disabled via SSL_OP_ALL) and adds optional support for 1/n-1
record splitting.
The latter is not enabled by default, since it's not typically used on
servers, but it should be enabled in web browsers since there are known
attacks in that case (see BEAST).
(Called "cut through" for historical reasons in this patch.)
Enables SSL3+ clients to send application data immediately following the
Finished message even when negotiating full-handshakes. With this
patch, clients can negotiate SSL connections in 1-RTT even when
performing full-handshakes.
Initial fork from f2d678e6e89b6508147086610e985d4e8416e867 (1.0.2 beta).
(This change contains substantial changes from the original and
effectively starts a new history.)
