If the media is windows and guestfs version is less than 1.17.18
raise a Fatal Error. The versions below this have a bug and
inspect_os will fail if the HKLM\SYSTEM\MountedDevices registry key
is missing. This key gets deleted by Microsoft Sysprep

Before libguestfs 1.18.4 you cannot shutdown the backend and then
relaunch it

Conflicts:
	image_creator/os_type/unix.py
	image_creator/version.py
	version

Don't try to scrub data unless the used guestfs appliance supports
it

On some systems it is kvm, on some others it is qemu-system-x86_64. On
32bit PC it is qemu-system-i386

Group the system preparation tasks to simple and advanced.

Remove constants BOOT_TIMEOUT, SHUTDOWN_TIMEOUT and CONNECTION_RETRIES
and add then as sysprep_parameters

This is needed since the input we get from the input dialogs is
always strings.

Fix some bugs and some other coding issues found using pylint

Fix _get_users method in windows.py to not list user accounts that
are disabled.

Make sure winexe returns error if a diskpart command fails

When booting the windows VM during sysprep, check if winexe works
before starting the system preparation tasks

When waiting for windows to boot, also check that the Windows VM
process is up.

This contains a wrapper class for winexe utility

This sysprep converts the windows image into a KMS client

When syspreping a Windows image, sleep for 10 seconds before you

Reset the LocalAccountTokenFilterPolicy registry key in RunOnce. This
key is set by hivex offline when you boot windows, it seems to have a
wrong value.

This can be used to add arbitrary attributes to the function it
decorates

Since all sysprep functions output a message when they get executed,
add the message printing functionality to the sysprep decorator

In windows the do_sysprep method shuts down the guestfs vm and boots
the image. This allows executing windows commands on the image remotely.

The user may define parameters needed by the os_type classes to perform
the system preparation tasks.

A new needed_sysprep_params method is added to os_type.OSBase that
returns a list with parameters that should be defined by the user.
