	It's more consistent with the rest of libvirt_qemud, though :-)

	I'm of two minds, really. Previously I would have always done
malloc()/memset() but when using glib I'd tend to use g_new0(). So, it's
handy to have a zeroing allocator.

	I guess I never previously relied on calloc() zeroing the memory since
that behaviour isn't reflected in its name.

	Again, wondering why you'd want to use libxml2's wrapper.
