Ok, so we just need to get rid of the constants in the public header
file, and remove these APis
virInterfacePtr virInterfaceLookupByMAC (virConnectPtr conn,
const unsigned char *mac);
int virInterfaceGetMAC (virInterfacePtr interface,
unsigned char *mac);
and change the remote_protocol.x file to use 'remote_nonnull_string'
instead of the fixed length mac addr on the wire.
And in the virInterfacePtr struct in src/datatypes.c also use the null
terminated string, instead of fixed byte array.

Daniel
