[libvirt] [PATCH 00/16] snapshot refactoring (incremental backup saga)

[Eric Blake]

A couple of these have seen the list before, but most of them are
new. The bulk of this series is about refactoring snapshot_conf.c into
smaller pieces that I can then reuse for implementing checkpoints,
without having to open-code the hierarchy algorithms a second time
(one of John's complaints against my v4 incremental backup series).

I suspect that src/vz/ builds may break on one or more of these
patches; I could not get a working vz build environment.

Eric Blake (16):
  test: Avoid use-after-free on virDomainSnapshotDelete
  snapshot: Use accessors for virDomainSnapshot members
  snapshot: Create virDomainMoment base class
  vbox: Clean up some snapshot usage
  snapshot: Drop virDomainSnapshotDef.current
  snapshot: Track current snapshot in virDomainSnapshotObjList
  snapshot: Add accessors for updating snapshot list relations
  snapshot: Access snapshot def directly when needed
  snapshot: Refactor list filtering
  snapshot: Factor out virDomainMomentDef class
  snapshot: Switch type of virDomainSnapshotObj.def
  snapshot: Rename virDomainSnapshotObjPtr
  snapshot: Rename file for virDomainMomentObj
  snapshot: Move snapshot list code into generic file
  snapshot: Tweaks to support new bulk dumpxml/import API
  backup: Introduce virDomainCheckpointPtr
