As a precursor to removing the code entirely later, disable the protocol
by default. Callers must use SSL_CTX_set_min_version to enable it.
This change also makes SSLv3_method *not* enable SSL 3.0. Normally
version-specific methods set the minimum and maximum version to their
version. SSLv3_method leaves the minimum at the default, so we will
treat it as all versions disabled. To help debugging, the error code is
switched from WRONG_SSL_VERSION to a new NO_SUPPORTED_VERSIONS_ENABLED.
This also defines OPENSSL_NO_SSL3 and OPENSSL_NO_SSL3_METHOD to kick in
any no-ssl3 build paths in consumers which should provide a convenient
hook for any upstreaming changes that may be needed. (OPENSSL_NO_SSL3
existed in older versions of OpenSSL, so in principle one may encounter
an OpenSSL with the same settings.)

This only works at TLS 1.2 and above as, before TLS 1.2, there is no way
to advertise support for Ed25519 or negotiate the correct signature
algorithm. Add tests for this accordingly.
For now, this is disabled by default on the verifying side but may be
enabled per SSL_CTX. Notably, projects like Chromium which use an
external verifier may need changes elsewhere before they can enable it.
(On the signing side, we can assume that if the caller gave us an
Ed25519 certificate, they mean for us to use it.)

Previously we only needed to be able to serve P-224 certificates, but
now we anticipate a need to be able to connect and validate them also.
Since this requires advertising support for P-224 in the handshake, we
need to support P-224 ECDHE too.
P-224 support is disabled by default and so clients need to both set the
enabled curves explicitly and set a maximum version of TLS 1.2.

Channel ID is incompatible with 0-RTT, so we gracefully decline 0-RTT
as a server and forbid their combination as a client. We'll keep this
logic around until Channel ID is removed.
Channel ID will be replaced by tokbind which currently uses custom
extensions. Those will need additional logic to work with 0-RTT.
This is not implemented yet so, for now, fail if both are ever
configured together at all. A later change will allow the two to
combine.

Once 0-RTT data is added to the current 0-RTT logic, the server will
trigger a write when processing incoming data via SSL_read. This means
SSL_read will block on transport write, which is something we've not
tried to avoid far (assuming no renegotiation).
The specification allows for tickets to be sent at half-RTT by
predicting the client Finished. By doing this we both get the tickets on
the wire sooner and avoid confusing I/O patterns. Moreover, we
anticipate we will need this mode for one of the QUIC stateless reject
patterns.
This is tested by always processing NewSessionTickets in the
ExpectHalfRTTData path on 0-RTT connections. As not other
implementations using BoGo may not do this, this is configurable via the
shim config.

The DTLS stack has two very different APIs for handling timeouts. In
non-blocking mode, timeouts are driven externally by the caller with
DTLSv1_get_timeout. In blocking mode, timeouts are driven by the BIO by
calling a BIO_ctrl with BIO_CTRL_DGRAM_SET_NEXT_TIMEOUT.
The latter is never used by consumers, so remove support for it.
BIO_CTRL_DGRAM_SET_NEXT_TIMEOUT implicitly depends on struct timeval
being used for timestamps, which we would like to remove. Without this,
the only public API which relies on this is the testing-only
SSL_CTX_set_current_time_cb which is BoringSSL-only and we can change at

In honor of CVE-2016-9244. Although that particular bug BoGo was already
testing since it uses 16 bytes here.
The empty session ID case is particularly worth testing to make sure we
don't get confused somewhere. RFC 5077 allows clients to offer tickets
with no session ID. This is absurd since the client then has no way of
detecting resumption except by lookahead. We'll never do this as a
client, but should handle it correctly as a server.

The TLS 1.2 and 1.3 state machines do the exact same thing at the
beginning. Let them process the ClientHello extensions, etc., and
finalize the certificate in common code. Once we start picking
parameters, we begin to diverge. Everything before this point is
arguably part of setting up the configuration, which is
version-agnostic.

In TLS 1.2, resumption's benefits are more-or-less subsumed by False
Start. TLS 1.2 resumption lifetime is bounded by how much traffic we are
willing to encrypt without fresh key material, so the lifetime is short.
Renewal uses the same key, so we do not allow it to increase lifetimes.
In TLS 1.3, resumption unlocks 0-RTT. We do not implement psk_ke, so
resumption incorporates fresh key material into both encrypted traffic
(except for early data) and renewed tickets. Thus we are both more
willing to and more interested in longer lifetimes for tickets. Renewal
is also not useless. Thus in TLS 1.3, lifetime is bound separately by
the lifetime of a given secret as a psk_dhe_ke authenticator and the
lifetime of the online signature which authenticated the initial
handshake.
This change maintains two lifetimes on an SSL_SESSION: timeout which is
the renewable lifetime of this ticket, and auth_timeout which is the
non-renewable cliff. It also separates the TLS 1.2 and TLS 1.3 timeouts.
The old session timeout defaults and configuration apply to TLS 1.3, and
we define new ones for TLS 1.3.
Finally, this makes us honor the NewSessionTicket timeout in TLS 1.3.
It's no longer a "hint" in 1.3 and there's probably value in avoiding
known-useless 0-RTT offers.

Until we've gotten it fully working, we should not mint any of these
SSL_SESSIONs, to avoid constraining future versions of our client code.
Notably, if any of our TLS 1.3 clients today serialized sessions, we
would need to rev the serialization format. Without opting into 0-RTT, a
TLS 1.3 client will create SSL_SESSIONs tagged as 0-RTT-capable but
missing important fields (ALPN, etc.). When that serialized session
makes its way to a future version of our client code, it would disagree
with the server about the ALPN value stored in the ticket and cause
interop failures.
I believe the only client code enabling TLS 1.3 right now is Chrome, and
the window is small, so it should be fine. But fix this now before it
becomes a problem.

This changes our resumption strategy. Before, we would negotiate ciphers
only on fresh handshakes. On resumption, we would blindly use whatever
was in the session.
Instead, evaluate cipher suite preferences on every handshake.
Resumption requires that the saved cipher suite match the one that would
have been negotiated anyway. If client or server preferences changed
sufficiently, we decline the session.
This is much easier to reason about (we always pick the best cipher
suite), simpler, and avoids getting stuck under old preferences if
tickets are continuously renewed. Notably, although TLS 1.2 ticket
renewal does not work in practice, TLS 1.3 will renew tickets like
there's no tomorrow.
It also means we don't need dedicated code to avoid resuming a cipher
which has since been disabled. (That dedicated code was a little odd
anyway since the mask_k, etc., checks didn't occur. When cert_cb was
skipped on resumption, one could resume without ever configuring a
certificate! So we couldn't know whether to mask off RSA or ECDSA cipher
suites.)
Add tests which assert on this new arrangement.

This simplifies a little code around EMS and PSK KE modes, but requires
tweaking the SNI code.
The extensions that are more tightly integrated with the handshake are
still processed inline for now. It does, however, require an extra state
in 1.2 so the asynchronous session callback does not cause extensions to
be processed twice. Tweak a test enforce this.
This and a follow-up to move cert_cb before resumption are done in
preparation for resolving the cipher suite before resumption and only
resuming on match.
Note this has caller-visible effects:
- The legacy SNI callback happens before resumption.
- The ALPN callback happens before resumption.
- Custom extension ClientHello parsing callbacks also cannot depend on
resumption state.
- The DoS protection callback now runs after all the extension callbacks
as it is documented to be called after the resumption decision.

Having that logic in two different places is a nuisance when we go to
add new checks like resumption stuff. Along the way, this adds missing
tests for the ClientHello cipher/session consistency check. (We'll
eventually get it for free once the cipher/resumption change is
unblocked, but get this working in the meantime.)
This also fixes a bug where the session validity checks happened in the
wrong order relative to whether tickets_supported or renew_ticket was
looked at. Fix that by lifting that logic closer to the handshake.

EnableAllCiphers is problematic since some (version, cipher)
combinations aren't even defined and crash. Instead, use the
SendCipherSuite bug to mask the true cipher (which is becomes arbitrary)
for failure tests. The shim should fail long before we get further.
This lets us remove a number of weird checks in the TLS 1.3 code.
This also fixes the UnknownCipher tests which weren't actually testing
anything. EnableAllCiphers is now AdvertiseAllConfiguredCiphers and
does not filter out garbage values.

This is in preparation for implementing the version extension and is

This means knobs like SendClientVersion and SendServerVersion deal with

SendFoo is just a weird post-processing bit on the handshake messages
while NegotiateVersion actually changes how BoGo behaves.)

This GREASEs cipher suites, groups, and extensions. For now, we'll
always place them in a hard-coded position. We can experiment with more
interesting strategies later.
If we add new ciphers and curves, presumably we prefer them over current
ones, so place GREASE values at the front. This prevents implementations
from parsing only the first value and ignoring the rest.
Add two new extensions, one empty and one non-empty. Place the empty one
in front (IBM WebSphere can't handle trailing empty extensions) and the
non-empty one at the end.
