5c57c60beb Deprecate SSL_get_client_certificate_types.
OpenSSL added SSL_get0_certificate_types and fixed the truncation (and
subsequent parse error) by adding an alternate copy of the data.
http://git.openssl.org/gitweb/?p=openssl.git;a=commit;h=9f27b1eec3175305e62eed87faa80e231f319ca0

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.

3213bed728 Remove GOST support code from ssl/
Also remove related quirk, SSL_OP_CRYPTOPRO_TLSEXT_BUG. Glue code is
left in for now.

ac61fa379f Implement TLS_FALLBACK_SCSV support for the client.
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.

See http://tools.ietf.org/html/draft-bmoeller-tls-downgrade-scsv-02.

b6333d600e Return per-certificate chain if extra chain is NULL.
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

858a88daf2 Equal preference cipher groups.
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.

adb739e1e5 False Start support.
(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.

95c29f3cd1 Inital import.
Initial fork from f2d678e6e89b6508147086610e985d4e8416e867 (1.0.2 beta).

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