Due to recent changes, changing the SSL session timeout from cert_cb is
not possible anymore since the new |SSL_SESSION| is initialized *after*
cert_cb is run. The alternative would be using |SSL_CTX_set_timeout| but
the specific |SSL_CTX| could be shared by multiple |SSL|s.
Setting a value on a per-connection basis is useful in case timeouts
need to be calculated dynamically based on specific certificate/domain
information that would be retrieved from inside cert_cb (or other
callbacks).
It would also be possible to set the value to 0 to prevent session
resumption, which is not otherwise doable in the handshake callbacks.

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.

This is in preparation for determining the cipher suite (which, in TLS
1.2, requires the certificate be known) before resumption.
Note this has caller-visible effects:
- cert_cb is now called whether resumption occurs or not. Our only
consumer which uses this as a server is Node which will require a
patch to fix up their mucking about with SSL_get_session. (But the
patch should be quite upstreamable. More 1.1.0-compatible and
generally saner.)
- cert_cb is now called before new_session_cb and dos_protection_cb.

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.

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.
