Always close fds returned by tempfile.mkstemp()

Share the md5sum and meta file if image is public

If the image gets registered as public allow anyone to read the
metadata and the md5sum file.

Change a ValueError exception to FatalError

Rename DiskDevice class to Image

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.

Enforce raw img format in libguestfs

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

Support python-sendfile 2.x

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.

Merge branch 'stable-0.1'

Minor fixes in output messages

Retry cleanup commands if they fail

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.

Remove progress bar for guestfs.launch() progress

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...

Fix a bug in image shrinking code

Credits go to Giannis Spiliopoulos <gspilio@admin.grnet.gr>

Fix bugs in bundle_volume module

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

Fix the image partitions in bundle_volume

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

Add new bundle_volume module

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

Handle keaboard interrupts and TERM signals.

Make the cow file size equal to the original media

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.

Fix minor typos

Leave 2048 sectors space at the end when shrinking

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

Allow readonly mount in DiskDevice class

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

Disable recovery proc if libguestfs ver < 1.17.14

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.

Remove the swap partition when shrinking

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.

Fix a bug introduced in commit e108efd285b34d5a28e

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

Add support for GUID Partition Tables

Switch to ansicolor for coloring & fix pep8 errors

Add progress bar in pithos upload & compute md5sum

Fix typos in var names

Add silent mode option

All printing had to be reordered and now it is done from a central point.

Correct image size computation

This commit fixes a bug where size method in DiskDevice returned the
payload size of the device one byte shorter than it actually was.

Beautify program's output.

Fix wrong variable name in progress_callback

Split DiskDevice constructor in 2 parts

In the constructor only variable initialization is performed. This is
needed because the constructor is executed before the DiskDevice
instance is appended to the device list, and if something fails there,
then the resources may be cleaned up in an incorrect order.

Add an extra yield in progress_generator

This is needed to suppress the StopIteration exception

Handle imported commands that aren't in the PATH

This fixes cases where a normal user tries to execute the program and
the program raises pbs.CommandNotFound exceptions because it tries to
import a command from sbin, which is not in the path.

Fix minor typos

Make DiskDevice.shrink() return the new disk size

Fix code for cleanup of image data

Use libguestfs to access the image
