[libvirt] [PATCH 0/6] Split the storage file driver impls from the storage driver backends

The storage driver backends currently register storage file backends as a side effect of initialization. This is fine right now while both run in the same libvirtd process, but in future the storage file backends will need to run in the hypervisor daemon which will be separate from the storage daemon. This small series splits them, makin the storage file backends be registered "on demand" Daniel P.
