[libvirt] [PATCH 00/20] Support for external checkpoints

[Peter Krempa]

This set consists of multiple parts:

The first 4 patches are a rebase of Eric's series to add
external checkpoint support to the XML. I posted them as
I had some conflicts to solve when rebasing them lately.

Patches 5-10 are a re-send of my previously posted series to
add ability to create external checkpoints. These are only
rebased and I did _not_ apply review feedback to them.

Patches 11-20 are new and consist of a few cleanups
and refactors to implement needed functionality to revert an
external snapshot. There are three new features:
1) creation of offline external snapshots
2) deletion of external snapshots (with a few limitations)
3) reverting of external snapshots

When this series will be closer to being "pushable" I'll post
another cleanup that will split out all snapshot related
code in qemu into a separate file as it's a mess right now.
