"A unified kernel image is a single EFI PE executable combining an EFI
stub loader, a kernel image, an initramfs image, and the kernel command
line.
[...]
Images of this type have the advantage that all metadata and payload
that makes up the boot entry is monopolized in a single PE file that can
be signed cryptographically as one for the purpose of EFI
SecureBoot."[1]
This commit adds a create-unified-kernel-image=true option to the
bootimg-efi plugin for creating a Unified Kernel Image[1] and installing
it into $BOOT/EFI/Linux/ with a .efi extension per the the Boot Loader
Specification[1][2]. This is useful for implementing Secure Boot.
systemd-boot is the only mainstream bootloader implementing the
specification, but GRUB should be able to boot the EFI binary, this
commit however doesn't implement the necessary changes to the GRUB
config generation logic to boot the Unified Kernel Image.

The empty wic plugin is used to create unformatted empty partitions for wic
images.
To use it you must pass "empty" as argument for the "--source" parameter in
the wks file. For example:
part foo --source empty --ondisk sda --size="1024" --align 1024
Also adds a selftest for this plugin where the 'Fstype' column from 'wic
ls' should be empty for the second partition as listed in
test_empty_plugin.wks.

Add unittests for bootimg-biosplusefi SourcePlugin in wic module.
First test check wic creation works correctly.
Second test uses qemu to boot image and checks that it has both
EFI and BIOS files in a single partition.

Added test_rawcopy_plugin_qemu test case and wks template.
This test builds ext4 rootfs image, copies it to the root
partition of the wic image using rawcopy plugin and
boots wic image in qemu.

Add a kickstart for an image that is not limited to use on x86 compatible
machines. This allows us to run more wic tests on non-x86 architectures.
