We will need OpenSSL 1.1.0 in order to test some of the features
expected for Go 1.8. However, 1.1.0 also disables (by default) some
things that we still want to test, such as RC4, 3DES and SSLv3. Thus
developers wanting to update the crypto/tls test data will need to build
OpenSSL from source.
This change updates the test data with transcripts generated by 1.1.0
(in order to reduce future diffs) and also causes a banner to be printed
if 1.1.0 is not used when updating.
(The test for an ALPN mismatch is removed because OpenSSL now terminates
the connection with a fatal alert if no known ALPN protocols are
offered. There's no point testing against this because it's an OpenSSL
behaviour.)

The RFC is clear that the Parameters in an AlgorithmIdentifer for an RSA
public key must be NULL. BoringSSL enforces this so we have strong
evidence that this is a widely compatible change.
Embarrassingly enough, the major source of violations of this is us. Go
used to get this correct in only one of two places. This was only fixed
in 2013 (with 4874bc9b). That's why lots of test certificates are
updated in this change.
Fixes#16166.

This change alters the certificate used in many tests so that it's no
longer self-signed. This allows some tests to exercise the standard
certificate verification paths in the future.

This is the second in a two-part change. See https://golang.org/cl/9415
for details of the overall change.
This change updates the supported signature algorithms to include
SHA-384 and updates all the testdata/ files accordingly. Even some of
the testdata/ files named “TLS1.0” and “TLS1.1” have been updated
because they have TLS 1.2 ClientHello's even though the server picks a
lower version.
Fixes#9757.

Currently an ECDHE handshake uses the client's curve preference. This
generally means that we use P-521. However, P-521's strength is
mismatched with the rest of the cipher suite in most cases and we have
a fast, constant-time implementation of P-256.
With this change, Go servers will use P-256 where the client supports
it although that can be overridden in the Config.

The renegotiation extension was introduced[1] due to an attack by Ray in
which a client's handshake was spliced into a connection that was
renegotiating, thus giving an attacker the ability to inject an
arbitary prefix into the connection.
Go has never supported renegotiation as a server and so this attack
doesn't apply. As a client, it's possible that at some point in the
future the population of servers will be sufficiently updated that
it'll be possible to reject connections where the server hasn't
demonstrated that it has been updated to address this problem.
We're not at that point yet, but it's good for Go servers to support
the extension so that it might be possible to do in the future.

The practice of storing reference connections for testing has worked
reasonably well, but the large blocks of literal data in the .go files
is ugly and updating the tests is a real problem because their number
has grown.
This CL changes the way that reference tests work. It's now possible to
automatically update the tests and the test data is now stored in
testdata/. This should make it easier to implement changes that affect
all connections, like implementing the renegotiation extension.
