[libvirt] [PATCH 05/20] Allow caps to be NULL when creating virDomainObjPtr instances

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

If no private data needs to be maintained, it can be useful
to create virDomainObjPtr instances without having a virCapsPtr
instance around. Adapt the virDomainObjNew() function to allow
for a NULL caps
