2fb2ffb660 Update aes.c for new ARM asm names.
In order to align ppc64le with the existing code, 4467e59b changed the
prefix for both the ARM and ppc64le AES assembly code to be “aes_hw_”.
However, it didn't update aes.c as well.

4467e59bc8 Add PPC64LE assembly for AES-GCM.
This change adds AES and GHASH assembly from upstream, with the aim of
speeding up AES-GCM.

The PPC64LE assembly matches the interface of the ARMv8 assembly so I've
changed the prefix of both sets of asm functions to be the same
("aes_hw_").

Otherwise, the new assmebly files and Perlasm match exactly those from
upstream's c536b6be1a (from their master branch).

3c6a1ea674 Apply version/wire mapping at a higher layer in runner.
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.)

65ac997f20 Implement draft-davidben-tls-grease-01.
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.

a78e6a5ab5 Switch from readdir_r back to readdir.
readdir and readdir_r have a sad history:
https://www.gnu.org/software/libc/manual/html_node/Reading_002fClosing-Directory.html
https://womble.decadent.org.uk/readdir_r-advisory.html
http://austingroupbugs.net/view.php?id=696

Martin Thomson reports that newer glibcs warn that readdir_r is
deprecated. Especially since this has been banished to libdecrepit
anyway, go ahead and honor that warning. OpenSSL also uses readdir, so
we're no worse than they are.

While I'm here, rewrite this to remove a useless layer of abstraction,
now that we've punted on supporting most platforms here. Also remove the
redundant documentation comment (there's one in the header already).

f3fbadeae0 Add tests for SSL_peek.
SSL_peek works fine for us, but OpenSSL 1.1.0 regressed this
(https://github.com/openssl/openssl/issues/1563), and we don't have
tests either. Fix this.

SSL_peek can handle all weird events that SSL_read can, so use runner
and tell bssl_shim to do a SSL_peek + SSL_peek + SSL_read instead of
SSL_read. Then add tests for all the events we may discover.

e34bcc91c0 Support default versions with set_{min,max}_proto_version.
Upstream makes 0 mean "min/max supported version". Match that behavior,
although call it "default" instead. It shouldn't get you TLS 1.3 until
we're ready to turn it on everywhere.

c8b6b4fe4a Only predict X25519 in TLS 1.3.
We'd previously been assuming we'd want to predict P-256 and X25519 but,
on reflection, that's nonsense. Although, today, P-256 is widespread and
X25519 is less so, that's not the right question to ask. Those servers
are all 1.2.

The right question is whether we believe enough servers will get to TLS
1.3 before X25519 to justify wasting 64 bytes on all other connections.
Given that OpenSSL has already shipped X25519 and Microsoft was doing
interop testing on X25519 around when we were shipping it, I think the
answer is no.

Moreover, if we are wrong, it will be easier to go from predicting one
group to two rather than the inverse (provided we send a fake one with
GREASE). I anticipate prediction-miss HelloRetryRequest logic across the
TLS/TCP ecosystem will be largely untested (no one wants to pay an RTT),
so taking a group out of the predicted set will likely be a risky
operation.

Only predicting one group also makes things a bit simpler. I haven't
done this here, but we'll be able to fold the 1.2 and 1.3 ecdh_ctx's
together, even.

2dc0204603 Don't return invalid versions in version_from_wire.
This is in preparation for using the supported_versions extension to
experiment with draft TLS 1.3 versions, since we don't wish to restore
the fallback. With versions begin opaque values, we will want
version_from_wire to reject unknown values, not attempt to preserve
order in some way.

This means ClientHello.version processing needs to be separate code.
That's just written out fully in negotiate_version now. It also means
SSL_set_{min,max}_version will notice invalid inputs which aligns us
better with upstream's versions of those APIs.

This CL doesn't replace ssl->version with an internal-representation
version, though follow work should do it once a couple of changes land
in consumers.

d2ba8891e0 Improve -valgrind error-handling.
Passing --quiet makes valgrind only print out errors, so we don't need
to suppress things. Combine that with checking valgrind's dedicated exit
code so we notice errors that happen before the "---DONE---" marker.

This makes that marker unnecessary for valgrind. all_tests.go was not
sensitive to this, but still would do well to have valgrind be silent.

7a4aaa4ce7 Fix TLS 1.3 fuzzer mode in Go.
Runner needs to implement fuzzer mode as well so we can record
transcripts from it. A bunch of tests were failing:

- 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.)

Now the only failing tests are the ones one would expect to fail.

786793411a Do not distinguish NULL and empty PSK identity hints.
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.
