In transition to removing it altogether, set SSL_MODE_NO_AUTO_CHAIN by

them to revert locally with SSL_(CTX_)clear_mode, but hopefully this was

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.

These don't make sense and mean some SSL_SESSIONs serialize and
deserialize as different values. If we ever managed to create an
SSL_SESSION without a time, it would never expire because time always
gets set to time(NULL). If we ever created an SSL_SESSION with a zero
timeout, the timeout would be... three? Once we start adjusting
time/timeout to issuance time, driving timeout to zero is actually
plausible, so it should work properly.
Instead, make neither field optional. We always fill both out, so this
shouldn't have any effects. If it does, the only effect would be to
decline to resume some existing tickets which must have been so old that
we'd want them to have expired anyway.

A renewed session does not refresh the timeout. Add tests for this in

also likely wish to tweak the parameters for 1.3 to account for (a)
ECDHE-PSK means we're only worried about expiring a short-circuited

We currently preferentially sign the largest hash available and
advertise such a preference for signatures we accept. We're just as
happy with SHA-256 and, all else equal, a smaller hash would be epsilon
more performant. We also currently claim, in TLS 1.3, we prefer P-384
over P-256 which is off.
Instead order SHA-256 first, next the larger SHA-2 hashes, and leave
SHA-1 at the bottom. Within a hash, order ECDSA > RSA-PSS > RSA-PKCS1.
This has the added consequence that we will preferentially pair P-256
with SHA-256 in signatures we generate instead of larger hashes that get
truncated anyway.
