The existing tests for this codepath require us to reconfigure the shim.
This will not work when TLS 1.3 cipher configuration is detached from
the old cipher language. It also doesn't hit codepaths like sessions
containing a TLS 1.3 version but TLS 1.2 cipher.
Instead, add some logic to the runner to rewrite tickets and build tests
out of that.

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 means knobs like SendClientVersion and SendServerVersion deal with

SendFoo is just a weird post-processing bit on the handshake messages

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.

This means ClientHello.version processing needs to be separate code.

SSL_set_{min,max}_version will notice invalid inputs which aligns us

- C and Go disagreed on what fuzzer mode did to TLS 1.3 padding. So we
fuzz more code, align Go with C. Fuzzer mode TLS 1.3 still pads but
just skips the final AEAD.
- The deterministic RNG should be applied per test, not per exchange. It
turns out, if your RNG is deterministic, one tends to pick the same
session ID over and over which confuses clients. (Resumption is
signaled by echoing the session ID.)

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

access_denied is only used to indicate client cert errors and Chrome
maps it to ERR_SSL_BAD_CLIENT_AUTH_CERT accordingly:
access_denied
A valid certificate was received, but when access control was
applied, the sender decided not to proceed with negotiation. This
message is always fatal.
We don't appear to be the cause of Chrome's recent
ERR_SSL_BAD_CLIENT_AUTH_CERT spike, but we should send these correctly
nonetheless.
If the early callback fails, handshake_failure seems the most
appropriate ("I was unable to find suitable parameters"). There isn't
really an alert that matches DoS, but internal_error seems okay?
internal_error
An internal error unrelated to the peer or the correctness of the
protocol (such as a memory allocation failure) makes it impossible
to continue. This message is always fatal.

This mechanism is incompatible with deploying draft versions of TLS 1.3.
Suppose a draft M client talks to a draft N server, M != N. (Either M or
N could also be the final standard revision should there be lingering
draft clients or servers.) The server will notice the mismatch and
pretend ClientHello.version is TLS 1.2, not TLS 1.3. But this will
trigger anti-downgrade signal and cause an interop failure! And if it
doesn't trigger, all the clever tricks around ServerHello.random being
signed in TLS 1.2 are moot.
We'll put this back when the dust has settled.

Although RFC 6066 recommends against it, some servers send a warning
alert prior to ServerHello on SNI mismatch, and, per spec, TLS 1.2
allows it.
We're fine here, but add a test for it. It interacts interestingly with
TLS 1.3 forbidding warning alerts because it happens before version
negotiation.

Changing parameters on renegotiation makes all our APIs confusing. This
one has no reason to change, so lock it down. In particular, our
preference to forbid Token Binding + renego may be overridden at the
IETF, even though it's insane. Loosening it will be a bit less of a
headache if EMS can't change.
https://www.ietf.org/mail-archive/web/unbearable/current/msg00690.html
claims that this is already in the specification and enforced by NSS. I
can't find anything to this effect in the specification. It just says
the client MUST disable renegotiation when EMS is missing, which is
wishful thinking. At a glance, NSS doesn't seem to check, though I could
be misunderstanding the code.
Nonetheless, locking this down is a good idea anyway. Accurate or not,
take the email as an implicit endorsement of this from Mozilla.

If cert_cb runs asynchronously, we end up repeating a large part of very
stateful ClientHello processing. This seems to be mostly fine and there
are few users of server-side cert_cb (it's a new API in 1.0.2), but it's
a little scary.
This is also visible to external consumers because some callbacks get
called multiple times. We especially should try to avoid that as there
is no guarantee that these callbacks are idempotent and give the same
answer each time.

This finishes getting rid of ssl_read_bytes! Now we have separate
entry-points for the various cases. For now, I've kept TLS handshake
consuming records partially. When we do the BIO-less API, I expect that
will need to change, since we won't have the record buffer available.
(Instead, the ssl3_read_handshake_bytes and extend_handshake_buffer pair
will look more like the DTLS side or Go and pull the entire record into
init_buf.)
This change opts to make read_app_data drive the message to completion
in anticipation of DTLS 1.3. That hasn't been specified, but
NewSessionTicket certainly will exist. Knowing that DTLS necessarily has
interleave seems something better suited for the SSL_PROTOCOL_METHOD
internals to drive.
It needs refining, but SSL_PROTOCOL_METHOD is now actually a half-decent
abstraction boundary between the higher-level protocol logic and
DTLS/TLS-specific record-layer and message dispatchy bits.

This is in preparation for switching finish_handshake to a
release_current_message hook. finish_handshake in DTLS is also
responsible for releasing any memory associated with extra messages in
the handshake.
Except that's not right and we need to make it an error anyway. Given
that the rest of the DTLS dispatch layer already strongly assumes there
is only one message in epoch one, putting the check in the fragment
processing works fine enough. Add tests for this.
This will certainly need revising when DTLS 1.3 happens (perhaps just a
version check, perhaps bringing finish_handshake back as a function that
can fail... which means we need a state just before SSL_ST_OK), but DTLS
1.3 post-handshake messages haven't really been written down, so let's
do the easy thing for now and add a test for when it gets more
interesting.
This removes the sequence number reset in the DTLS code. That reset
never did anything becase we don't and never will renego. We should make
sure DTLS 1.3 does not bring the reset back for post-handshake stuff.
(It was wrong in 1.2 too. Penultimate-flight retransmits and renego
requests are ambiguous in DTLS.)

Ridiculous as it is, the protocol does not forbid packing HelloRequest
and Finished into the same record. Add a test for this case.

Alas, we will need a version fallback for TLS 1.3 again.
This deprecates SSL_MODE_SEND_FALLBACK_SCSV. Rather than supplying a
boolean, have BoringSSL be aware of the real maximum version so we can
change the TLS 1.3 anti-downgrade logic to kick in, even when
max_version is set to 1.2.
The fallback version replaces the maximum version when it is set for
almost all purposes, except for downgrade protection purposes.

This is basically the same as BadECDHECurve-TLS13. That the client picks
a share first but the server picks the curve type means there's less
redundancy to deal with.
