Move sharable PCI handling functions to domain_addr.[ch], and
change theirs prefix from 'qemu' to 'vir':
- virDomainPCIAddressAsString;
- virDomainPCIAddressBusSetModel;
- virDomainPCIAddressEnsureAddr;
- virDomainPCIAddressFlagsCompatible;
- virDomainPCIAddressGetNextSlot;
- virDomainPCIAddressReleaseSlot;
- virDomainPCIAddressReserveAddr;
- virDomainPCIAddressReserveNextSlot;
- virDomainPCIAddressReserveSlot;
- virDomainPCIAddressSetFree;
- virDomainPCIAddressSetGrow;
- virDomainPCIAddressSlotInUse;
- virDomainPCIAddressValidate;
The only change here is function names, the implementation itself
stays untouched.
Extract common allocation code from DomainPCIAddressSetCreate
into virDomainPCIAddressSetAlloc.
