made STREAM_CRYPTO_METHOD_TLS_CLIENT only support TLSv1.0 (no v1.1/v1.2). This is a commonly used method (by various functions in PHP source itself, common software like piwik, roundcube, davical, owncloud and others, and libraries like zendframework, PEAR Net-IMAP/Sieve/SMTP) so it should support modern TLS versions. ok robert@
