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.

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
'ctypes'.

Move ECC SSL extensions to the end.
WebSphere Application Server 7.0 appears to be intolerant of an empty
extension at the end. To that end, also ensure we never send an empty
padding extension.
Fix limit checks in ssl_add_clienthello_tlsext and
ssl_add_serverhello_tlsext.
Some of the limit checks reference p rather than ret. p is the original
buffer position, not the current one. Fix those and rename p to orig so
it's clearer.

effectively starts a new history.)
