Subject: Allow forced setting of TLS1.1 and TLS1.2 protocols with
X-Git-Tag: 2.2.24~36

Allow forced setting of TLS1.1 and TLS1.2 protocols with
the -f command-line switch, and adapt the output to more accurately
report what SSL/TLS protocol was negotiated (use SSL_get_version()
instead of SSL_CIPHER_get_version()).
