Piotr Pelplinski ede6d97e3c blobstore: add inflate call
Inflate call can be used on thin provisioned blob or clones.

Function allocates all unallocated clusters on specified blob and:
 - For clones, copies data from backing blob.
 - For thin provisioned blobs, clusters are zeroed.

After this call all dependency from specified blob is removed
what allows deletion i.e. snapshots.
