Remove no longer reachable CRL path validation code

crl_akid_check now always, on success, leaves CRL_SCORE_SAME_PATH in the
score. (Note CRL_SCORE_ISSUER_CERT contains CRL_SCORE_SAME_PATH.) This
means the recursive validation logic in check_crl_path never runs, and
we can remove a very worrying re-entrant call in the validator. The CRL
must be issued by either the issuer, or some ancestor in the chain.
(This also matches the behavior of the new validator.)

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.
