11:31 a.m.
Extract PCI handling related structs that could be shared
with other drivers.
List of structs moved to virpci.h and new names:
qemuDomainPCIAddressBus -> virDomainPCIAddressBus
qemuDomainPCIAddressBusPtr -> virDomainPCIAddressBusPtr
_qemuDomainPCIAddressSet -> virDomainPCIAddressSet
qemuDomainPCIAddressSetPtr -> virDomainPCIAddressSetPtr
qemuDomainPCIConnectFlags -> virDomainPCIConnectFlags
Also, extract qemuDomainPCIAddressAsString function and rename
it into virPCIDeviceAddressAsString.
