I screwed up the |EVP_CIPHER| parameters for XTS when I first imported
it, and there were no tests to catch it. (The problem was that
|EVP_CIPH_XTS_MODE| means “the key size is actually twice what it says
here.”)
With these changes, OpenSSL's tests pass.
(Along the way, make a few other things about XTS slightly less
decrepit.)

The keylog BIO is internally synchronized by the SSL_CTX lock, but an

preparation for switching Chromium to use a separate SSL_CTX per profile

It will also be useful for routing up SSLKEYLOGFILE in WebRTC. There,

mistake in https://boringssl-review.googlesource.com/1843 which flipped it
from client-only to server-only.
- It only runs in TLS 1.2, so one could bypass it by just negotiating TLS 1.1.
Upstream added it as part of their Suite B mode, which requires 1.2.
Move it elsewhere. Though we do not check the entire chain, leaving that to the
certificate verifier, signatures made by the leaf certificate are made by the
SSL/TLS stack, so it's reasonable to check the curve as part of checking
