Remove unused X509_LOOKUP_by_* functions.

None of the built-in X509_LOOKUP functions support
X509_LOOKUP_by_fingerprint, X509_LOOKUP_by_issuer_serial, or
X509_LOOKUP_by_alias. We also made X509_LOOKUP_METHOD opaque and haven't
added the corresponding X509_LOOKUP_meth_set_* functions[*], so it is
currently impossible to usefully use these.

I found no callers which use or implement these, which makes sense. The
reason to implement X509_LOOKUP is to plug it into the X509_STORE, which
only cares about lookup by subject.

So just remove them. We can put it back later if it comes up.

[*] Actually it looks like we haven't added any way to make a custom
X509_LOOKUP_METHOD at all yet. I guess it hasn't come up yet.

Update-Note: Some unused functions were removed.

BoringSSL

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.

Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.

Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.

BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.

Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
