crypto: account for new 1.1.0 SSL APIs
Browse files Browse the repository at this point in the history
This is cherry-picked from PR nodejs#8491 and tidied up. This change does
*not* account for the larger ticket key in OpenSSL 1.1.0. That will be
done in a follow-up commit as the 48-byte ticket key is part of Node's
public API.

rvagg: removed BORINGSSL defines before landing
