[PATCH 3/3] util: storagefile: Track whether a virStorageSource was auto-detected

[Peter Krempa <pkrempa@xxxxxxxxxx>]

When formatting an inactive or migratable XML we will need to suppress
backing chain members which were detected from the disk to keep
semantics straight. This means we need to record, whether a
virStorageSource originates from autodetection.
