Shouldn't both be required?  EG  We don't want NULL or "" for new_name,
right?

The comments should at least indicate @new_name cannot be NULL or empty
string.

Although it seems remoteDomainRename could pass along a NULL that it
doesn't seem virDomainObjListRename would be very happy to STREQ against.

ACK as long as the NonNullArg is replaced...
