A provider could be linked against a different version of libcrypto than the version of libcrypto that loaded the provider. Different versions of libcrypto could define opaque types differently. It must never occur that a type created in one libcrypto is used directly by the other libcrypto. This will cause crashes. We can "cheat" for "built-in" providers that are part of libcrypto itself, because we know that the two libcrypto versions are the same - but not for other providers. To ensure this does not occur we use different types names for the handful of opaque types that are passed between the core and providers.
