As a precursor to removing the code entirely later, disable the protocol by default. Callers must use SSL_CTX_set_min_version to enable it. This change also makes SSLv3_method *not* enable SSL 3.0. Normally version-specific methods set the minimum and maximum version to their version. SSLv3_method leaves the minimum at the default, so we will treat it as all versions disabled. To help debugging, the error code is switched from WRONG_SSL_VERSION to a new NO_SUPPORTED_VERSIONS_ENABLED. This also defines OPENSSL_NO_SSL3 and OPENSSL_NO_SSL3_METHOD to kick in any no-ssl3 build paths in consumers which should provide a convenient hook for any upstreaming changes that may be needed. (OPENSSL_NO_SSL3 existed in older versions of OpenSSL, so in principle one may encounter an OpenSSL with the same settings.)
