H A Dqcow2-refcount.c32b6444d Tue Sep 03 08:09:52 GMT 2013 Max Reitz <mreitz@redhat.com> qcow2-cluster: Expand zero clusters

Add functionality for expanding zero clusters. This is necessary for
downgrading the image version to one without zero cluster support.

For non-backed images, this function may also just discard zero clusters
instead of truly expanding them.
