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

https://bugzilla.redhat.com/show_bug.cgi?id=1138516 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.
