Per spec, the server sends it iff it sends the extension in ServerHello. There
is no need to probe for whether Finished is or isn't sent. NSS is strict about
this (wait_new_session_ticket never transitions to wait_change_cipher without a
NewSessionTicket message), so this is safe.
Reset tlsext_ticket_expected in ssl_scan_serverhello_tlsext to ensure state
from the initial handshake doesn't confuse renegotiation. This is another one
of those per-handshake states that should be systematically reset on each
handshake. For now, reset it properly at least.

tls_session_secret_cb is used for EAP-FAST which computes the master secret
externally and enters the abbreviated handshake. It appears to only have been
working because ssl3_check_finished would drive it into the appropriate state
afterwards. That, in turn, only has been working because EAP-FAST misuses the
session ticket extension for some other field, so ssl3_check_finished isn't a
no-op.
Instead, set s->hit so it follows the abbreviated state machine directly.
If we ever build wpa_supplicant with BoringSSL, this will require some testing.

This avoids duplicating the code to build the final premaster in PSK and

the premaster secret now proceeds in four steps:
1. If a PSK key exchange (alg_a), look up the pre-shared key.
2. Compute the premaster secret based on alg_k. If PSK, it's all zeros.
3. If a PSK key exchange (alg_a), wrap the premaster in a struct with the
pre-shared key.
4. Use the possibly modified premaster to compute the master secret.

This is the first of reorganizing state between connection state and handshake
state. The existing set are retained in cert_st for the server; they are server
configuration. The client gets a copy in s->s3->tmp alongside other handshake
state.
With other handshake state moved there, hopefully we can reset that state in
one go and possibly not even maintain it when there is no handshake in
progress. Rather than currently where we sometimes confused connection state
and handshake state and have to reset as appropriate on renegotiate.
While I'm here, document the fields and name them something more useful than
