This removes the last case where the server generates an RSA key for the

still remains.
Leave the APIs for now, but they don't do anything anymore.

commit), but isn't especially helpful at this point.

Without SSLv2, all cipher suite values are 2 bytes. Represent them as a
uint16_t and make all functions pass those around rather than pointers.
This removes SSL_CIPHER_find as it's unused.

Don't retain curve IDs in serialized form; serialization only happens when
writing and reading from the wire. The internal representation is a uint16_t
which matches the range of the value and avoids all the checks for the first
byte being 0.
This also fixes a bug in tls1_check_ec_tmp_key's suite B logic; the || should
have been &&, though now it's gone.
This doesn't relieve some of the other assumptions about curve IDs:
tls1_set_curves still assumes that all curve IDs are under 32, and
tls1_ec_curve_id2nid still assumes 0 is not a valid curve ID. Add a
compile-time assert and a comment to document this. We're up to 28 now, so this
may well need to be revised sooner or later.
Remove SSL_get_shared_curve as it's new and unused API, using it in a loop is
O(N^3), and lets us simplify a function.

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'.

Building without RSA support is unreasonable. Changes were made by
running

find . -type f -name *.h | xargs unifdef -m -U OPENSSL_NO_RSA
using unifdef 2.10 and some newlines were removed manually.

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.

With this change, calling SSL_enable_fallback_scsv on a client SSL* will
cause the fallback SCSV to be sent.
This is intended to be set when the client is performing TLS fallback
after a failed connection. (This only happens if the application itself
implements this behaviour: OpenSSL does not do fallback automatically.)
The fallback SCSV indicates to the server that it should reject the
connection if the version indicated by the client is less than the
version supported by the server.

If an application calls the macro SSL_CTX_get_extra_chain_certs
return either the old "shared" extra certificates or those associated
with the current certificate.
This means applications which call SSL_CTX_use_certificate_chain_file
and retrieve the additional chain using SSL_CTX_get_extra_chain_certs
will still work. An application which only wants to check the shared
extra certificates can call the new macro
SSL_CTX_get_extra_chain_certs_only

This change implements equal-preference groups of cipher suites. This
allows, for example, a server to prefer one of AES-GCM or ChaCha20
ciphers, but to allow the client to pick which one. When coupled with
clients that will boost AES-GCM in their preferences when AES-NI is
present, this allows us to use AES-GCM when the hardware exists and
ChaCha20 otherwise.
(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.

(This change contains substantial changes from the original and
effectively starts a new history.)
