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

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

From: "Daniel P. Berrange" <berrange@xxxxxxxxxx>

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
