A few times libvirt users manually setting mac addresses have complained of a networking failure that ends up being due to a multicast mac address being used for a guest interface. This patch prevents that by logging an error and failing if a multicast mac address is encountered in each of the three following cases: 1) domain xml <interface> mac address. 2) network xml bridge mac address. 3) network xml dhcp/host mac address. There are several other places where a mac address can be input that aren't controlled in this manner because failure to do so has no consequences (e.g., if the address will be used to search through existing interfaces for a match). The RNG has been updated to add multiMacAddr and uniMacAddr along with the existing macAddr, and macAddr was switched to uniMacAddr where appropriate.
