[Libguestfs] [PATCH v2 00/17] v2v: add --in-place mode

[Roman Kagan]

This series is a second 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 14 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 (17):
  v2v: debug gc via at_exit hook
  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 determing the guest firmware
  v2v: move target_bus_assignment ahead of main
  v2v: factor out copying of output data
  v2v: factor out preserving overlays for debugging
  v2v: move main to the end of file
  v2v: drop redundant umount_all() and shutdown()
  v2v: factor out opening guestfs handle
  v2v: factor out populating guestfs with overlays
  v2v: add --in-place mode
  v2v: document --in-place
  v2v: add test for --in-place

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)
