[Libguestfs] [PATCH v3 00/13] v2v: add --in-place mode

This series is an attempt to add a mode of virt-v2v operation where it
leaves the config and disk image conversion, rollback on errors,
registering with the destination hypervisor, etc. to a third-party
toolset, and performs only tuning of the guest OS to run in the
KVM-based hypervisor.

The first 10 patches are just refactoring and rearrangement of the code,
factoring the implementation details out into separate functions (one
logical step at a time).  This results in main() compacted from a few
hundreds lines to a few dozens containing only coarse steps and making
the scenarios easy to follow.

The last three patches add the new mode, the description of it in the
man page, and a test for it, resp.

Roman Kagan (13):
  v2v: factor out opening input VM
  v2v: factor out overlay creation
  v2v: factor out populating targets list
  v2v: factor out size checks
  v2v: factor out actual guest transformation
  v2v: factor out determining the guest firmware
  v2v: factor out copying of output data
  v2v: factor out preserving overlays for debugging
  v2v: drop redundant umount_all() and shutdown()
  v2v: factor out opening and populating guestfs handle
  v2v: add --in-place mode
  v2v: document --in-place
  v2v: add test for --in-place

---
changes from v2:
 - top-down arrangement of function defitinions
 - branching of scenarios using a dedicated type

changes from v1:
 - include refactoring patches before the --in-place ones
 - split --in-place patches into code, doc, and test for easier review
   (bisectability maintained)
