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

Specifically, TLS 1.3 draft 18's ticket_age_add logic will require some

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
authentication rather than forward secrecy and (b) two hours is too
