The further thought occurs that a v2u1 app might be using a v2u1+N
GSS-API implementation (there's no version negotiation between the two).

For the case of re-keys (if we ever implement re-key with extra async
context tokens) we must then... what? introduce a new major status code
for GSS_Process_context_token()?  I think that would do.
