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

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.

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.

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.

When embedding a rootfs image (e.g. 'rootfs-dir') as a partition we
might want to keep the stock fstab for that image. In such a case, use
this option to not update the fstab and use the stock one instead.
This option allows you to specify which partitions get the fstab
updated and which get the stock fstab.
The option matches the argument you can pass to wic itself where the
same action is performed but for all the partitions.

--fstype=ext4 --label export --align 1024 --no-fstab-update

This reverts part of oe-core eecbe62555, which was a previous attempt
to solve the Y2038 problem. This is now solved centrally in e2fsprogs,
so doesn't need to be dealt with in wic.
We don't revert the commit entirely, to retain the warning if a
filesystem has small inodes.

Previously the bootimg-pcbios wic plugin was not respecting
the --label option provided from the wks file. The plugin
was setting the label to 'boot'. With this fix, the --label
option is use. If no option are specified, then the default
is 'boot'.

Since Linux 5.4 a new read-only filesystem is available, erofs.
Compared to squashfs it offers much better read performance with and
without compression enabled.
It suppports two optional compressors, lz4 and lz4hc.
>From the mkfs.erofs man page:
EROFS is a new enhanced lightweight linux read-only filesystem with
modern designs (eg. no buffer head, reduced metadata, inline
xattrs/data, etc.) for scenarios which need high-performance read-only
requirements, e.g. Android OS for smartphones and LIVECDs.
It also provides fixed-sized output compression support, which improves
storage density, keeps relatively higher compression ratios, which is
more useful to achieve high performance for embedded devices with
limited memory since it has unnoticable memory overhead and page cache
thrashing.
This commit adds support for three new filesystem targets:
erofs: erofs without compression
erofs-lz4: erofs with lz4 compresssion enabled
erofs-lz4hc: erofs with lz4hc compression enabled

Incremental build in Docker fails with:
OSError: [Errno 18] Invalid cross-device link
when source and destination are on different overlay filesystems.
Rather than adding fallback code to every call site, use a new wrapper
in bitbake which detects this case and falls back to shutil.move
which is slower but will handtle the overlay docker filesystems correctly.

Modern dosfstools automatically determines the appropriate size
and will error out if something that doesn't make sense is
supplied on the command line.
