Don't retain curve IDs in serialized form; serialization only happens when
writing and reading from the wire. The internal representation is a uint16_t
which matches the range of the value and avoids all the checks for the first
byte being 0.
This also fixes a bug in tls1_check_ec_tmp_key's suite B logic; the || should
have been &&, though now it's gone.
This doesn't relieve some of the other assumptions about curve IDs:
tls1_set_curves still assumes that all curve IDs are under 32, and
tls1_ec_curve_id2nid still assumes 0 is not a valid curve ID. Add a
compile-time assert and a comment to document this. We're up to 28 now, so this
may well need to be revised sooner or later.
Remove SSL_get_shared_curve as it's new and unused API, using it in a loop is
O(N^3), and lets us simplify a function.

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.

ssl3_get_new_session_ticket is sensible and fills in a session_id for stateless

codepath in ssl3_client_hello which allows for resuming sessions with empty

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.

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.
