This is prefactoring for a coming change to the shim that will write
handoff and handback messages (which are serialized SSLConnection
objects) to the transcript.
This breaks the slightly tenuous ordering between the runner and the
shim. Fix the runner to wait until the shim has exited before
appending the transcript.

If the caller asked for the base to be treated as secret, we should
provide that. Allowing unbounded inputs is not compatible with being
constant-time.
Additionally, this aligns with the guidance here:
https://github.com/HACS-workshop/spectre-mitigations/blob/master/crypto_guidelines.md#1-do-not-conditionally-choose-between-constant-and-non-constant-time
Update-Note: BN_mod_exp_mont_consttime and BN_mod_exp_mont now require
inputs be fully reduced. I believe current callers tolerate this.
Additionally, due to a quirk of how certain operations were ordered,
using (publicly) zero exponent tolerated a NULL BN_CTX while other
exponents required non-NULL BN_CTX. Non-NULL BN_CTX is now required
uniformly. This is unlikely to cause problems. Any call site where the
exponent is always zero should just be replaced with BN_value_one().

implementation, this can be quadratic. As this is an API fuzzer, not an
actual attack surface, this is not of much interest in itself, but
bounding this will let the fuzzers fuzz faster.

The new APIs are SSL_CTX_set_strict_cipher_list() and
SSL_set_strict_cipher_list(). They have two motivations:
First, typos in cipher lists can go undetected for a long time, and
can have surprising consequences when silently ignored.
Second, there is a tendency to use superstition in the construction of
cipher lists, for example by "turning off" things that do not actually
exist. This leads to the corrosive belief that DEFAULT and ALL ought
not to be trusted. This belief is false.

|SSL_SESSION_from_bytes| now takes an |SSL_CTX*|, from which it uses the
|X509_METHOD| and buffer pool. This is our API so we can do this.
This also requires adding an |SSL_CTX*| argument to |SSL_SESSION_new|
for the same reason. However, |SSL_SESSION_new| already has very few
callers (and none in third-party code that I can see) so I think we can
get away with this.

There are no longer any consumers of these APIs.
These were useful back when the CBC vs. RC4 tradeoff varied by version
and it was worth carefully tuning this cutoff. Nowadays RC4 is
completely gone and there's no use in configuring these anymore.
To avoid invalidating the existing ssl_ctx_api corpus and requiring it
regenerated, I've left the entries in there. It's probably reasonable
for new API fuzzers to reuse those slots.
