Crash in tortls/cert_matches_key with openssl 1.0.2p

Our unit test, tortls/cert_matches_key, does some questionable stuff that is not compatible with openssl 1.0.2p.

Namely, it calls EVP_PKEY_asn1_new(999, 0, NULL, NULL), which now returns NULL.

Looking at the test, I'm not sure what it's trying to do with this -- it's making a bogus public key method with a "compare" function that will always return "1". Later, it's using this thing to construct bogus PKEY objects.

This, like a lot of other tortls.c tests, is way too tightly coupled to openssl internals.

Looks good to me! I think it has merge conflicts on 0.3.4 and newer, but I didn't try very hard to resolve them. (They might be easy to resolve though.)

Okay; I've merged and resolved the conflicts. I'm going to keep an eye on Jenkins in the next day or so, since this kind of thing is prone to have some minor issue somewhere.
