Reland: Use CRYPTO_BUFFER APIs instead of X509 when building with BoringSSL.

Browse Source 
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.
