[libvirt] [PATCH 0/3] Add stateDir for storage driver and use for disk backend

Using the network (and domain) for reference, add a 'stateDir' for the
Storage Driver in order to save off pool and/or volume specific information
into a live running area.

This is useful for the disk backend where volume creation can define a
specific name and target format type to use; however, that information
cannot be encoded into the 'parted' data used to create the partition(s)
on the disk.  Thus the data is lost for refresh and restart/reload.

The following patches will add the stateDir, then the infrastructure for
storage volume xml to be saved off, and finally saving/using that data
for the refresh, restart/reload path for the disk backend driver.

  storage: Introduce virStorageVol{Save|Delete}Status
