[Cole Robinson <crobinso redhat com>]

The following 2 patches implement virStorageVolCreateXMLFrom for the
storage driver and the FS storage backend.

Changes from v1:
- Mark origvol as building in driver implementation
- Make sure driver is locked when relocking pool object
- Simplify sparse file detection with memcmp
- Allocate read buffer on the heap.

Thanks,
