Using CRYPTO_BUFFERs instead of legacy X509 objects offers memory and security gains, and will provide binary size improvements as well once the default list of built-in certificates can be removed; the code dealing with them still depends on the X509 API. Implemented by splitting openssl_identity and openssl_certificate into BoringSSL and vanilla OpenSSL implementations.
