Subject: [PATCH] tls: compile with OpenSSL 1.1.0

The init functions are not longer required in OpenSSL 1.1 so I dropped
them.

TLSv1_client_method() should not be used because it enables only the
TLSv1.0 protocol. Better is to use SSLv23_client_method() which enable
all the protocols including TLSv1.2. With this functions SSLv2 and SSLv3
is theoretically possible but as of today those protocols are usually
build-time disabled.
To avoid all this OpenSSL 1.1 provides TLS_client_method() which is aim
to provide to highest TLS protocol version (same as
SSLv23_client_method() but it is deprecated in 1.1).
