When we have been told to use the UUID we should also update the fstab
to make use of PARTUUID instead of hard-coding the device in question.
This will make the resulting image much more portable.

The WIC's 'part' can now give a name for GPT partition in WKS file.
It's similar to '--label', but is naming partintions instead file systems.
It's required by some bootloaders to partitions have specified names.

Create an option to wic doesn't change fstab file, the final
fstab file will be same that in rootfs and wic doesn't update
file, e.g adding a new mount point.
Users can control the fstab file content in base-files recipe.
This is useful if you want to only create an partition but not
add fstab mount point or add new mount point using label e.g:
LABEL=recovery /recovery auto defaults 0 1

wic avoided adding /boot to fstab for no reason.
This exception was hardcoded in the wic code.
There is no need for this as mountpoint in .wks file is an optional
field. It can be used only if user wants to have partitions
automatically mounted on system boot.

wic updates /etc/fstab on root partition if there are
valid mount points in .wks
When wic runs from bitbake this can cause incorrect results
or even breakage of other tasks working with the same rootfs
directory in parallel with do_image_wic.
Implemented copying rootfs directory to a temporary location
using copyhardlinktree before updating fstab to avoid conflicts with
other tasks working with the same rootfs directory.

Total number of partitions should be taken into account when calculating
real partition number for msdos partition table. The number can be
different for the 4th partition: it can be 4 if there are 4 partitions in
the table and 5 if there are more than 4 partitions in the table. In the
latter case number 4 is occupied by extended partition.

Wic updates fstab if mount points are specified in .wks.
After partition images are created the original fstab is restored.
However, if exception is raised when partition image being prepared
wic doesn't restore original fstab. This can cause duplication of
added lines in fstab when 'wic create' runs next time.
Wrapping call of 'prepare' method and restoring original fstab
even if exception occurs should fix this.

Partition UUID for msdos partitioning is based on a 4 bytes long
system identifier. Wic uses random number to generate system
identifier. For the numbers starting with 0 partition uuid is
shorter, which makes wic images non-bootable as kernel expects
8 charactest in PARTUUID parameter.
Padded system identifier with '0' when generating partition UUID
to make it always 8 characters long. This should fix the boot
issue.

If we are both having a bootloader and a U-Boot environment file, we
can end up with two entries using "--source rawcopy" and "--no-table",
and since they reuse the same file [1], their cleanup handlers will
try to delete the same file twice. So make sure we only do it once.
[1] Although they reuse the same file, the resulting output is
correct, so it appears the file is accessed in properly sequential
order.

Disk operations were spread over DirectPlugin, DiskImage and Image
code making the code hard to understand.
Renamed Image class to PartitionedImage.
Removed DiskImage class.
Moved disk operations to PartitionedImage.
There was an implicit support for multiple disks: if different devices
were specified in .wks file (e.g. --ondisk sda and --ondisk sdb), wic
would theoretically generate multiple images. This is quite confusing
option and the code supporting it was broken for a long time. The same
effect (multiple output images) can be achieved in obvious and clear
way - by using multiple .wks files.
This functionality was removed. PartitionedImage works only with
one image. This makes the code less complex and easier to maintain.

It was a typo in current code: mktemp was used instead of
mkdtemp to create work directory. This is fixed by using
mkdtemp.
Create work directory as a subdirectory of output directory
to make sure both are on the same partition to make moving
of result image faster.
This also fixes possible disk space issues as mkdtemp uses
TMPDIR, TEMP or TMP environment variables to get default value
of its 'dir' parameter. Those variables are usually pointing
to /tmp, which is not the best location to create huge images.
