This is in preparation for implementing the version extension and is
probably what we should have done from the beginning as it makes
intolerance bugs simpler.
This means knobs like SendClientVersion and SendServerVersion deal with
the wire values while knobs like NegotiateVersion and MaxVersion deal
with logical versions. (This matches how the bugs have always worked.
SendFoo is just a weird post-processing bit on the handshake messages
while NegotiateVersion actually changes how BoGo behaves.)

Plain PSK omits the ServerKeyExchange when there is no hint and includes
it otherwise (it should have always sent it), while other PSK ciphers
like ECDHE_PSK cannot omit the hint. Having different capabilities here
is odd and RFC 4279 5.2 suggests that all PSK ciphers are capable of
"[not] provid[ing] an identity hint".
Interpret this to mean no identity hint and empty identity hint are the
same state. Annoyingly, this gives a plain PSK implementation two
options for spelling an empty hint. The spec isn't clear and this is not
really a battle worth fighting, so I've left both acceptable and added a
test for this case.
See also https://android-review.googlesource.com/c/275217/. This is also
consistent with Android's PskKeyManager API, our only consumer anyway.

Implement in both C and Go. To test this, route config into all the
sign.go functions so we can expose bugs to skip the check.
Unfortunately, custom private keys are going to be a little weird since
we can't check their curve type. We may need to muse on what to do here.
Perhaps the key type bit should return an enum that includes the curve?
It's weird because, going forward, hopefully all new key types have
exactly one kind of signature so key type == sig alg == sig alg prefs.

TLS 1.3 defines a new SignatureScheme uint16 enum that is backwards
compatible on the wire with TLS1.2's SignatureAndHashAlgorithm. This
change updates the go testing code to use a single signatureAlgorithm
enum (instead of 2 separate signature and hash enums) in preparation for
TLS 1.3. It also unifies all the signing around this new scheme,
effectively backporting the change to TLS 1.2.
For now, it does not distinguish signature algorithms between 1.2 and
1.3 (RSA-PSS instead of RSA-PKCS1, ECDSA must match curve types). When
the C code is ready make a similar change, the Go code will be updated
to match.

Previously, SSL_ECDH_METHOD consisted of two methods: one to produce a
public key to be sent to the peer, and another to produce the shared key
upon receipt of the peer's message.
This API does not work for NEWHOPE, because the client-to-server message
cannot be produced until the server's message has been received by the
client.
Solve this by introducing a new method which consumes data from the
server key exchange message and produces data for the client key
exchange message.

This injects an interface to abstract between elliptic.Curve and a
byte-oriented curve25519. The C implementation will follow a similar
strategy.
Note that this slightly tweaks the order of operations. The client sees
the server public key before sending its own. To keep the abstraction
simple, ecdhCurve expects to generate a keypair before consuming the
peer's public key. Instead, the client handshake stashes the serialized
peer public value and defers parsing it until it comes time to send
ClientKeyExchange. (This is analogous to what it was doing before where
it stashed the parsed peer public value instead.)

yaSSL has a couple of bugs in their DH client implementation. This
change works around the worst of the two.
Firstly, they expect the the DH public value to be the same length as
the prime. This change pads the public value as needed to ensure this.
Secondly, although they handle the first byte of the shared key being
zero, they don't handle the case of the second, third, etc bytes being
zero. So whenever that happens the handshake fails. I don't think that
there's anything that we can do about that one.

In particular, it assumes a reliable, in-order channel. And it requires that
the peer send handshake fragments in order. Retransmit and whatnot are not
implemented. The peer under test will be expected to handle a lossy channel,
but all loss in the channel will be controlled. MAC errors, etc., are fatal.
