The existing tests for this codepath require us to reconfigure the shim.
This will not work when TLS 1.3 cipher configuration is detached from
the old cipher language. It also doesn't hit codepaths like sessions
containing a TLS 1.3 version but TLS 1.2 cipher.
Instead, add some logic to the runner to rewrite tickets and build tests
out of that.

This is still rather a mess with how it's tied to SSL_AEAD_CTX_new
(probably these should get encapsulated in an SSL_AEAD struct), but this
avoids running the TLS 1.3 nonce logic on fake AEADs. This is impossible
based on cipher version checks, but we shouldn't need to rely on it.
It's also a little tidier since out_mac_secret_len is purely a function
of algorithm_mac.

We currently preferentially sign the largest hash available and
advertise such a preference for signatures we accept. We're just as
happy with SHA-256 and, all else equal, a smaller hash would be epsilon
more performant. We also currently claim, in TLS 1.3, we prefer P-384
over P-256 which is off.
Instead order SHA-256 first, next the larger SHA-2 hashes, and leave
SHA-1 at the bottom. Within a hash, order ECDSA > RSA-PSS > RSA-PKCS1.
This has the added consequence that we will preferentially pair P-256
with SHA-256 in signatures we generate instead of larger hashes that get
truncated anyway.

SSL_write has messy semantics around retries. As a sanity-check, it does
pointer and length checks and requires the original and retry SSL_write
pass the same buffer pointer.
In some cases, buffer addresses may change but still include the
original data as a prefix on the retry. Callers then set
SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER to skip the pointer check. But, in
that case, the pointer may have been freed so doing a comparison is
undefined behavior.
Short-circuiting the pointer equality check avoids this problem.
