Rename DiskDevice class to Image and move it to a seperate module.
Also, don't let the user access the os_type/* modules directly. In
Image class create the `os' member variable that will host an
appropriate instance of one of the OSBase classes.

Don't let libguestfs guess the format of the provided image. Enforce
it to treat the image as raw.

snf-image-creator removed /var/tmp if the directory was empty

Support both versions (1.2.x and 2.x) of python-sendfile. In
v1.2.x (py-sendfile) the returning value of the sendfile function is a
tuple, where in v2.x (pysendfile) it's a simple integer.

The cow file when creating images or the temporary image file when
bundling the host system may be large. Allow the user to overwrite
the directory under which those files get created.

Handle correct extended partitions with id 0xf

Add a new try_fail_repeat function that wraps cleanup system commands
and retries them if they fail. There are cases where commands like
dmsetup, umount and losetup -d may fail with device is busy. In most
of the cases, sleeping for halve a second and retrying does the job.

In Guestfs you get notifications about progress on some functions like
launch() by registring callback functions. When using guestfs from python,
this is fragile. If the callback functions raises an exception, you end up
with segmentation fault. It is better to completely remove the progress
monitoring from launch().

Also do a code cleanup

The partition table of the image is created correct. The partitions
are not yet filled.

Nothing is working yet

Check the file system usage and accordingly reduce the size of the
last partition in the image.

Create a sparse file under /mnt in the size of the root hard disk
and copy the mbr into this file. Not yet workable.

This is not yet workable but it will host the code for creating
images out of a running system.

The former is older but there are packages for it in distros like
Ubuntu.

The size of the cow file was hardcoded to 1G. This was buggy, because
for a big image, the resize operation could fill up the cow file and
fail.

Fixed many `E127 continuation line over-indented for visual indent'
errors

Most partition manipulation programs leave 2048 sector empty space
after the last partition.

Add an option to DiskDevice's mount method to allow readonly mount

In older versions of libguestfs, the recovery process did not close
the file descriptors it inherited. This could case problems if the
parent process had open pipes.

All image-creator components now output messages using an instance
of one of the output classes.

If the swap partition is the last partition in the media, then it can
be safely removed. The image-creator will save enough info in the
SWAP metadata to recreate it.

This is needed because otherwise setup.py fails on some systems. Also
do some more cleanup.

Not all needed code parts where updated when the size() method in
DiskDevice class was abandoned in favor of the size attribute.
