this will require to change sig format or at least make new subpacket for sernum.
besides it will not solve problem with revoking current sigs because they have
no such number.

I think it's enough to identify the sig by its creation time.
I don't think it's normal to have several sigs created at the same time,
and even if there is several sigs with the same creation time, well, they all
are revoked by single revocation sig that refers to this creation time.
