qemu: Converting DHCP and ARP functions to domain conf
QEMU driver has two functions: qemuGetDHCPInterfaces() and qemuARPGetInterfaces() that are being used inside only one single function. They can be turned into generic functions that other drivers can use. This commit move both from QEMU driver tree to domain conf tree.
