Bitrot: auto-initialization of OpenSSL 1.1.0

The functions SSL_library_init(), SSL_load_error_strings() and
OpenSSL_add_ssl_algorithms() are deprecated in OpenSSL 1.1.0.

Instead the library auto-initializes.  Though it is possible to
call OPENSSL_init_crypto() and OPENSSL_init_ssl() for explicit
control over initialization, for now there is no apparent reason
to do so.  This may change, so explicit initialization might yet
become necessary.
