[libvirt PATCH v3 00/10] external snapshot revert fixes
This fixes reverting external snapshots to not error out in cases where
it should work and makes it correctly load the memory state when
reverting to snapshot of running VM.
This discards v2 completely and makes changes to v1:
- moves qemuSaveImageStartProcess to qemu_process as
qemuProcessStartWithMemoryState
- change it to use cookie from memory state file instead of
using cookie from snapshot xml
- comments improvements
- introduces new helpers to start and stop decompression process
- reintroduces <externalSnapshot/> capability
