This is actually the way we manage updates so it's not a regression,
people trying to compile master spice-server should have master spice-protocol.
To compile in this specific case you don't need spice-common update but
obviously you want the spice-common patch in (as it should produce the updated
file in spice-protocol).

I think identity macros are useful as they allow a bit of independence
between specific commit even if they could introduce some potential
problems (is up to the user to use them or not).
