Libguestfs supports passing an ISO image as a source of virtio windows
drivers to v2v.
That support, however, looks too heavy-weight: in order to access those
drivers, a separate guestfs handle is created (and thus a new emulator
process is started), which runs until v2v triggers garbage collection.
This series attempts to make it simpler and lighter-weight, by making
the relevant code more local, and by hot-adding the image into the main
guestfs handle if supported by the backend.
Roman Kagan (4):
v2v: consolidate virtio-win file copying
v2v: copy virtio drivers without guestfs handle leak
v2v: drop useless forced gc
v2v: reuse main guestfs for virtio win drivers iso

changes since v1:
- rebased to latest master (in particular, updated usage of string
functions)
- add missing and remove excessive parentheses
- reorder patches
- preserve support for backends with no hot-add capability
