Fix iOS 1 SSL connection
Detect if we're talking to iOS 1 `if (connection->device->version == 0)` and set `SSL_CTX_set_min_proto_version(ssl_ctx, 0);` to support SSL3. iOS 1 doesn't understand TLS1_VERSION, it can only speak SSL3_VERSION. However, modern OpenSSL is usually compiled without SSLv3 support. So if we set min_proto_version to SSL3_VERSION on an OpenSSL instance which doesn't support it, it will just ignore min_proto_version altogether and fall back to an even higher version. To avoid accidentally breaking iOS 2.0+, we set min version to 0 instead.
