[libvirt PATCH 00/30] introduce external snapshot delete support

[Pavel Hrdina]

This implements virDomainSnapshotDelete API to support external
snapshots. The support doesn't include flags
VIR_DOMAIN_SNAPSHOT_DELETE_CHILDREN and
VIR_DOMAIN_SNAPSHOT_DELETE_CHILDREN_ONLY as it would add more complexity
and IMHO these flags should not existed at all.
