mod_http_oauth2: Record hash of client_id to allow future verification
RFC 6819 section 5.2.2.2 states that refresh tokens MUST be bound to the
client. In order to do that, we must record something that can
definitely tie the client to the grant. Since the full client_id is so
large (why we have this client_subset function), a hash is stored
instead.
