Bring in compatibility for OpenSSL 1.1 style init functions.

This adds OPENSSL_init_crypto and OPENSSL_init_ssl, as well
thread safety modifications for the existing LibreSSL init
functions.  The initialization routines are called automatically
by the normal entry points into the library, as in newer OpenSSL
