First, allow for wic to be given a filesystem UUID to be used when
creating a filesystem. When not provided, wic will generate the UUID to
be used. Next, when --use-uuid is passed, we update the fstab to mount
things via UUID (and if not found, then use PARTUUID) as UUID is more
portable.

The '--label' argument should work for '--source rawcopy' as it does for

With systemd, the mounting of the swap partition is handled via systemd
and will mount it, regardless of if PARTUUID is parsed or not. systemd
has a runtime dependency on util-linux-mount so PARTUUID for regular
mount points will be handled correctly. Make all partitions that we add
to the image make use of UUIDs for maximum portability.

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.

This fixes the issue that if you don't have mtools installed on the host
thus causing host contamination, that the correct binaries would be selected
from the native sysroot.

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

It can be useful to have multiple partitions with '--source bootimg-partition'
but different content.
E.g. for TI AM335x, one boot partition can contain an first stage
bootloader ("MLO"), while the real bootloader and kernel plus devicetree
are in another one.
Patch allows to specify multiple IMAGE_BOOT_FILES with optional "_label-XXX"
or "_uuid-XXX" overrides.
E.g. with this patch, a .wks file with
| part --source bootimg-partition ... --label=mlo --active
| part --source bootimg-partition ... --label=boot0
| part --source bootimg-partition ... --label=boot1
and a recipe with
| IMAGE_BOOT_FILES_label-mlo = "\
| MLO-${MACHINE}.img;MLO \
| "
|
| IMAGE_BOOT_FILES_label-boot0 = "\
| u-boot-${MACHINE}.img;u-boot.img \
| zImage \
| "
|
| IMAGE_BOOT_FILES_label-boot1 = "${IMAGE_BOOT_FILES_label-boot0}"
|
| WICVARS += " \
| IMAGE_BOOT_FILES_label-mlo \
| IMAGE_BOOT_FILES_label-boot0 \
| IMAGE_BOOT_FILES_label-boot1 \
| "
is possible. It will create one partition with the MLO and two redundant
ones with the uboot + kernel.

The most portable way to specifiy a root device in a disk image that we
create is to use PARTUUID rather than /dev/sda2. As background, both
GPT and MBR tables provide valid UUID values for each partition and the
Linux Kernel contains the logic to parse this value. With this change
we can now boot the default disk images when used as any valid block
device that the included kernel uses. This for example means that
VirtualBox can be used to run vmdk without changes as it uses IDE for
the virtual disk controller.

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.

At the moment, when building images with IMAGE_FSTYPES=wic one ends up
depending on wic-tools and thus syslinux and grub-efi even when not
using those at all. Ideally, building an image with wic should only
build the tools and components really needed.
The problem is that "wic-tools" is needed also for the manual
invocations of wic, in which case everything that might be needed has to
be built in advance.
Replaced dependency on wic-tools with dependency to a much shorter set
of tools that wic uses almost for any image: 'parted', 'gptfdisk',
'dosfstools' and 'mtools'.

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.
