* virStorageEncryptionFormat is called from both
virDomainDiskDefFormat and virStorageVolTargetDefFormat. The proper
indentation in the generated XML depends on the caller. My earlier
patch to fix the incorrect indentation for the domain XML broke the
indentation for the storage XML. This patch adopts Laine's
suggestion of requring the caller of virStorageEncryptionFormat to
provide an unsigned int with the number of spaces the output should
be indented. The patch modifies both callers to provide the
additional argument.
* Add a regression test for the domain XML
