This is a generic functionality that takes a set of files and create a
boot parition based on IMAGE_BOOT_FILES var, allow to sepcify the
variable name so a BSP plugin can extend this and re-use the
functionality.

Adds features to explicitly write zeros to the start of the
partition. This is useful to overwrite old content like
filesystem signatures which may be re-recognized otherwise.
The new features can be enabled with
'--soucreparams="[fill|size=<N>[S|s|K|k|M|G]][,][bs=<N>[S|s|K|k|M|G]]"'
Conflicting or missing options throw errors.
The features are:
- fill
Fill the entire partition with zeros. Requires '--fixed-size' option
to be set.
- size=<N>[S|s|K|k|M|G]
Set the first N bytes of the partition to zero. Default unit is 'K'.
- bs=<N>[S|s|K|k|M|G]
Write at most N bytes at a time during source file creation.
Defaults to '1M'. Default unit is 'K'.

The issue with installing the kernel image to both rootfs
and boot partition is that some systems rely on the kernel image in
rootfs and not in the boot partition.
This leads to duplication of the kernel image, which can cause
unnecessary storage usage.
This patch provides a solution to the problem by adding a new
parameter "install-kernel-into-boot-dir" to the wic kickstart file.
If this parameter is set to 'true', the plugin will install the
kernel image to the boot partition. If the parameter is set to
'false', the plugin will skip installing the kernel image, avoiding
duplication.

Add support for formatting a disk with a hybrid MBR & GPT partition
scheme. In this scheme, the primary partitioning method is GPT, but a
valid MBR header is also written than can point to a subset of the GPT
partitions on the disk (any partitions marked with the `--mbr` flag will
be included in this MBR). The primary purpose of this method is to allow
for SoCs that can only find a bootloader in an MBR partition to use GPT
once the bootloader is running. As an example, older versions of the
Raspberry Pi firmware can only parse MBR partitions to find a kernel (or
other bootloader like u-boot), but once those have booted GPT partitions
can be used.
In addition to the partitions annotated with the `--mbr`, a "protective"
GPT partition of type 0xEE is added, as the existence of such a
partition is the indication to tooling that this a hybrid MBR and that
the GPT partition table should be parsed instead.

The kickstart parser defaults fstype to "vfat". This leads to an attempt
to create an empty file system even for regions configured with "--no-table"
if used without fstype when no --sourceparams given.
The fix tests for fstype "none" or no_table in Partition prepare method.
This will omit the file system creation an the potential error for small
region with --no-table option.

I've encountered issues reproducing initramfs and UKI image builds,
which will be fixed with this patch.
1. initramfs
There's a symbolic link to /sbin/init, which is appended to the cpio archive after creation.
The links timestamp needs to be static and the cpio append command needs the '--reproducible' flag to produce deterministic outcomes.
2. Unified Kernel Image
'--preserve-dates' is required for a static 'Time/Date' entry.
I've added '--enable-deterministic-archives' although in my case this
didn't change anything.

Add argument --hidden to avoid MS Windows prompting to format
partition after flashing to a USB stick, SD card on another media.
Set Bit 0 (RequiredPartition) to mark that the partition is
required for the platform to function on GUID Partition Table
(GPT).
The new argument simplifies setting RequiredPartition on GPT
through a WKS file and the default imager plugin. Otherwise,
without this feature, to achieve the same result a new imager
plugin has to be implemented and set in WIC_CREATE_EXTRA_ARGS.

This is a bit of a compatibility issue more than anything. Some devices
get upset if the FAT file system contains less blocks than the
partition.
The fixed-size argument is currently respected by the partition creation
step but not by the file system creation step. Let's make it so the file
system respects this value as well.

The logic in this script validates that the length of data sections are
evenly divisible by the block size. On most systems the block size is
4KB and all is good. Some systems though, such as ppc64le, have a block
size larger then 4KB. For example on a POWER9 based ppc64le system, the
block size is 64KB.
This results in this script failing with errors like this when building
wic images:
|440, in _do_get_mapped_ranges
| assert extent_len % self.block_size == 0
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| AssertionError
In this case the data section size was 268KB and the block size was
64KB, resulting in the above assert failure.

This allows to specify partition with fstype=none in the wks file
to have partition created but without following mkfs. The none fstype
is in the list already but the usage is not documented.
Example;
part /data --ondisk mmcblk0 --fstype=none --align 4096 --fixed-size 512
will create a partition, filesystem may be created manualy on the host
or target and data will be preserved if the device is reflashed using
same wks. Works with bmaptool and probably does not work with dd.
Use case is persistent filesystem/data between reflashing of the image.

Commit 20d43a2 allows changes in fstab for the / mount. However, if the
fstab contains / already then this results in two entries for / in the
fstab, which is confusing and results in systemd producing errors on
boot:
systemd-fstab-generator[11101]: Failed to create unit file
/run/systemd/generator/-.mount, as it already exists. Duplicate entry
in /etc/fstab?
Wic should be extended to support merging mount points in fstab, but as
we're about to release revert the patch that introduced this change as
it hasn't been in a release yet, and the issue which prompted the patch
in the first place can be revisited post-release.
