This change makes the runner tests (in ssl/test/runner) act like a
normal Go test rather than being a Go binary. This better aligns with
some internal tools.
Thus, from this point onwards, one has to run the runner tests with `go
test` rather than `go run` or `go build && ./runner`.
This will break the bots.

Allow configuring digest preferences for the private key. Some
smartcards have limited support for signing digests, notably Windows
CAPI keys and old Estonian smartcards. Chromium used the supports_digest
hook in SSL_PRIVATE_KEY_METHOD to limit such keys to SHA1. However,
detecting those keys was a heuristic, so some SHA256-capable keys
authenticating to SHA256-only servers regressed in the switch to
BoringSSL. Replace this mechanism with an API to configure digest
preference order. This way heuristically-detected SHA1-only keys may be
configured by Chromium as SHA1-preferring rather than SHA1-requiring.
In doing so, clean up the shared_sigalgs machinery somewhat.

Rather than sniff for ClientHello, just fall through to standard logic
once weird cases are resolved.
This means that garbage will now read as WRONG_VERSION rather than
UNKNOWN_PROTOCOL, but the rules here were slightly odd anyway. This also
means we'll now accept empty records before the ClientHello (up to the
empty record limit), and process records of the wrong type with the
usual codepath during the handshake.
This shouldn't be any more risk as it just makes the ClientHello more
consistent with the rest of the protocol. A TLS implementation that
doesn't parse V2ClientHello would do the same unless it still
special-cased the first record. All newly-exposed states are reachable
by fragmenting ClientHello by one byte and then sending the record in

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.

This is a really dumb API wart. Now that we have a limited set of curves that
are all reasonable, the automatic logic should just always kick in. This makes
set_ecdh_auto a no-op and, instead of making it the first choice, uses it as
the fallback behavior should none of the older curve selection APIs be used.
Currently, by default, server sockets can only use the plain RSA key exchange.

See upstream's bd891f098bdfcaa285c073ce556d0f5e27ec3a10. It honestly seems
kinda dumb for a client to do this, but apparently the spec allows this.
Judging by code inspection, OpenSSL 1.0.1 also allowed this, so this avoids a
behavior change when switching from 1.0.1 to BoringSSL.
Add a test for this, which revealed that, unlike upstream's version, this
actually works with ecdh_auto since tls1_get_shared_curve also needs updating.

This causes any unexpected handshake records to be met with a fatal
no_renegotiation alert.
In addition, restore the redundant version sanity-checks in the handshake state
machines. Some code would zero the version field as a hacky way to break the
handshake on renego. Those will be removed when switching to this API.
The spec allows for a non-fatal no_renegotiation alert, but ssl3_read_bytes
makes it difficult to find the end of a ClientHello and skip it entirely. Given
that OpenSSL goes out of its way to map non-fatal no_renegotiation alerts to
fatal ones, this seems probably fine. This avoids needing to account for
another source of the library consuming an unbounded number of bytes without
returning data up.

After sharding the session cache for fallbacks, the numbers have been pretty
good; 0.03% on dev and 0.02% on canary. Stable is at 0.06% but does not have
the sharded session cache. Before sharding, stable, beta, and dev had been
fairly closely aligned. Between 0.03% being low and the fallback saving us in
all but extremely contrived cases, I think this should be fairly safe.
Add tests for both the cipher suite and protocol version mismatch checks.
