Thinking aloud: Should this visit 'self.prefix or self.name', rather
than letting callers see None?  If we did that, we could simplify
c_enum_const() back to 2 parameters, and update all callers to just
blindly pass the prefix instead of the enum name.  On the other hand, I
think that's a bit too much churn, and I don't see what it would buy us
that we don't already have with a 3-arg c_enum_const().

So I'm fine with the version you have here as-is (modulo any obvious
rebase to pass self._prefix based on my comments on 2).
