123db57009 Measure session->timeout from ticket issuance.
The distinction for full handshakes is not meaningful (the timestamp is
currently the start of the handshake), but for renewed sessions, we
currently retain the timestamp of the original issuance.

Instead, when minting or receiving tickets, adjust session->time and
session->timeout so that session->time is the ticket issuance time.

This is still not our final TLS 1.3 behavior (which will need a both
renewable and non-renewable times to honor the server ticket lifetime),
but it gets us closer and unblocks handling ticket_age_add from TLS 1.3
draft 18 and sends the correct NewSessionTicket lifetime.

This fixes the ticket lifetime hint which we emit on the server to
mirror the true ticket lifetime. It also fixes the TLS 1.3 server code
to not set the ticket lifetime hint. There is no need to waste ticket
size with it, it is no longer a "hint" in TLS 1.3, and even in the TLS
1.3 code we didn't fill it in on the server.

Note this assumes that, for external calls of these functions, the build
configuration of the consumer and BoringSSL match in this regard. (But
it doesn't actually matter because the issue is only on XP.)

a048678cd6 Move some fields from tmp to hs.
This releases memory associated with them after the handshake. Note this
changes the behavior of |SSL_get0_certificate_types| and
|SSL_get_client_CA_list| slightly. Both functions now return NULL
outside of the handshake. But they were already documented to return
something undefined when not called at the CertificateRequest.

A survey of callers finds none that would care. (Note
SSL_get_client_CA_list is used both as a getter for the corresponding
server config setter and to report client handshake properties. Only the
latter is affected.) It's also pretty difficult to imagine why a caller
would wish to query this stuff at any other time, and there are clear
benefits to dropping the CA list after the handshake (some servers send
ABSURDLY large lists).

97227dc52d Replace keywrap AEADs with upstream's APIs.
This finally removes the last Android hack. Both Chromium and Android
end up needing this thing (Chromium needs it for WebCrypto but currently
uses the EVP_AEAD version and Android needs it by way of
wpa_supplicant).

On the Android side, the alternative is we finish upstream's
NEED_INTERNAL_AES_WRAP patch, but then it just uses its own key-wrap
implementation. This seems a little silly, considering we have a version
of key-wrap under a different API anyway.

It also doesn't make much sense to leave the EVP_AEAD API around if we
don't want people to use it and Chromium's the only consumer. Remove it
and I'll switch Chromium to the new---er, old--- APIs next roll.

part of OpenSSL versions as well.

5fd1807d95 Implement SSL_CTX_set1_curves_list()
This function is used by NGINX to enable specific curves for ECDH from a
configuration file. However when building with BoringSSL, since it's not
implmeneted, it falls back to using EC_KEY_new_by_curve_name() wich doesn't
support X25519.

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).

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.

0c0a94d07b Better explain usage of CBB_flush
The high-level documentation for CBB describes using CBB_flush when a
child goes out of scope, but the function level documentation for
CBB_flush is less clear that CBB_flush will result in the CBB being
safe to use after the children go out of scope.

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.
