David Benjamin 3cfeb9522b Disable SSLv3 by default.
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.)
