I'm not quite quire we need to export these functions.
With the recent changes, we've gotten to the point that we're not
even passing a virZPCIDeviceAddress to them, but rather they have
the very same signature as the regular virPCIDeviceAddress...
So it should be possible to just make them static and only call
them from the virDomainPCIAddressReserveAddr() and friends, right?
Which is where I was hoping we could eventually get. Or did I
miss something?
I think this would make things complex. If either PCI address or
zPCI address exists, we have to do more checks for calling
virDomainPCIAddressReserveAddr(). And there are amounts of
code calling ***IsWanted() to call ***ReserveNext***(). I think
keeping them separately is better.
Everything else looks good.
