SSL_get_current_cipher is documented by upstream to return the cipher actually
being used. However, because it reads s->session, it returns information
pertaining to the session to be offered if queried before ServerHello or early
in an abbreviated handshake.
Logic around s->session needs more comprehensive cleanup but for just this
function, defining it to be the current outgoing cipher is close to the current
semantics but for fixing the initial state (s->session->cipher is populated
when sending CCS). Store it in the SSL_AEAD_CTX which seems a natural place to
associate state pertaining to a connection half.

This cuts down on one config knob as well as one case in the renego
combinatorial explosion. Since the only case we care about with renego
is the client auth hack, there's no reason to ever do resumption.
Especially since, no matter what's in the session cache:
- OpenSSL will only ever offer the session it just established,
whether or not a newer one with client auth was since established.
- Chrome will never cache sessions created on a renegotiation, so
such a session would never make it to the session cache.
- The new_session + SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION
logic had a bug where it would unconditionally never offer tickets
(but would advertise support) on renego, so any server doing renego
resumption against an OpenSSL-derived client must not support
session tickets.
This also gets rid of s->new_session which is now pointless.

There's multiple different versions of this check, between
s->s3->have_version (only works at some points), s->new_session (really
weird and not actually right), s->renegotiate (fails on the server
because it's always 2 after ClientHello), and s->s3->tmp.finish_md_len
(super confusing). Add an explicit bit with clear meaning. We'll prune
some of the others later; notably s->renegotiate can go away when
initiating renegotiation is removed.
This also tidies up the extensions to be consistent about whether
they're allowed during renego:
- ALPN failed to condition when accepting from the server, so even
if the client didn't advertise, the server could.
- SCTs now *are* allowed during renego. I think forbidding it was a
stray copy-paste. It wasn't consistently enforced in both ClientHello
and ServerHello, so the server could still supply it. Moreover, SCTs
are part of the certificate, so we should accept it wherever we accept
certificates, otherwise that session's state becomes incomplete. This
matches OCSP stapling. (NB: Chrome will never insert a session created
on renego into the session cache and won't accept a certificate
change, so this is moot anyway.)

The generic RC4 implementation may read and write just past the end of the
buffer; when input and output are aligned, it always reads an RC4_CHUNK at a
time. It appropriately masks off and preserves the excess bytes off the end, so
this can only have practical effects if it crosses a page boundary. There's an
alignment check, so that can't happen; page boundaries are always aligned. But
it makes ASan unhappy and strictly speaking is a memory error.
Instead, fall through to the generic codepath which just reads it byte by byte.

Some minor changes to the test format were made to account for test

Otherwise, the biggest difference in test format is that the ad-hoc
