65fb425811 Remove version-specific cipher lists.
There are no longer any consumers of these APIs.

These were useful back when the CBC vs. RC4 tradeoff varied by version
and it was worth carefully tuning this cutoff. Nowadays RC4 is
completely gone and there's no use in configuring these anymore.

To avoid invalidating the existing ssl_ctx_api corpus and requiring it
regenerated, I've left the entries in there. It's probably reasonable
for new API fuzzers to reuse those slots.

f01f42a2ce Negotiate ciphers before resumption.
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.

4eb95ccfd6 Parse ClientHello extensions before deciding on resumption.
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.

75f9914e17 Align TLS 1.2 and 1.3 server session validity checks.
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.

e6f2221423 Enforce record-layer version numbers.
We used to enforce after the version was set, but stopped enforcing with
TLS 1.3. NSS enforces the value for encrypted records, which makes sense
and avoids the problems gating it on have_version. Add tests for this.

231a475355 Test bad records at all cipher suites.
We have AEAD-level coverage for these, but we should also test this in
the TLS stack, and at maximum size per upstream's CVE-2016-7054.

da4789e412 Fix BoGo HelloVerifyRequest version handling.
3c6a1ea674 switched what layer handled
the DTLS version mapping but forgot to correct the HelloVerifyRequest
logic to account for this.

Thanks to Jed Davis for noticing this.

abbbee10ad Detach TLS 1.3 cipher configuration from the cipher language.
TLS 1.3 ciphers are now always enabled and come with a hard-coded
preference order.

7bb1d292cb Forbid using exporters during a renego.
They will get very confused about which key they're using. Any caller
using exporters must either (a) leave renegotiation off or (b) be very
aware of when renegotiations happen anyway. (You need to somehow
coordinate with the peer about which epoch's exporter to use.)

4199b0d190 Add tests which modify the shim ticket.
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.

079b394c49 Always enable GREASE for TLS 1.3 NewSessionTicket.
On the client we'll leave it off by default until the change has made it
through Chrome's release process. For TLS 1.3, there is no existing
breakage risk, so always do it. This saves us the trouble of having to
manually turn it on in servers.
