Unfortunately, this driver suffers a lot from Wycheproof's Java
heritgate, but so it goes. Their test formats bake in a lot of Java API
mistakes.

Currently we only check that the underlying EC_METHODs match, which
avoids the points being in different forms, but not that the points are
on the same curves. (We fixed the APIs early on so off-curve EC_POINTs
cannot be created.)
In particular, this comes up with folks implementating Java's crypto
APIs with ECDH_compute_key. These APIs are both unfortunate and should
not be mimicked, as they allow folks to mismatch the groups on the two
multiple EC_POINTs. Instead, ECDH APIs should take the public value as a
byte string.
Thanks also to Java's poor crypto APIs, we must support custom curves,
which makes this particularly gnarly. This CL makes EC_GROUP_cmp work
with custom curves and adds an additional subtle requirement to
EC_GROUP_set_generator.
Annoyingly, this change is additionally subtle because we now have a
reference cycle to hack around.

Unlike the Scoped* types, bssl::UniquePtr is available to C++ users, and
offered for a large variety of types. The 'extern "C++"' trick is used
to make the C++ bits digestible to C callers that wrap header files in
'extern "C"'.

This and the following commits will import NIST's ECC test vectors.
Right now all our tests pass if I make P-224 act like P-521, which is
kind of embarrassing. (Other curves are actually tested, but only
because runner.go tests them against BoGo.)
