[PATCH v2 0/7] re-fork wic pcbios and efi plugins

[Henning Schild <henning.schild@siemens.com>]

changes since v1:
  - efi plugin forked as well
  - systemd-boot support in efi plugin enabled
  - common functionality in utility library
  - test case for system-boot
  - "cp -a" moved to "find exec cp" because of ubuntu
  - changed wks files to exclude boot from root and mount it

The forked plugins have gotten out of sync with the last wic version
bumps. And the original fork was not exactly minimal or made for easy
maintenance.

This series does a re-fork of the two plugins with the aim to come up
with something readable, minimal and maintainable.

There used to be a special case for grub-efi where the actual kernel and
initrd would remain in the root partition, which kind of allowed kernel
updates with apt-get. Now all three bootloaders (systemd-boot now works
as well) place bootloader, config and boot artifacts in a
boot-partition.

Kernel updates with apt-get are now consistantly "broken". That
consistency very likely is not too bad. A generic solution for this
feature (if wanted) will need to be found. Covering not just these three
bootloaders but possibly also u-boot and efibootguard.

Henning Schild (7):
  wic: reset our plugin forks to OE upstream for re-forking
  wic: add utility library for common bits of isar plugins
  wic: apply the actual fork changes to our pcbios plugin fork
  wic: clean up wic class in terms of isar variables
  wic: apply the actual fork changes to our efi plugin fork
  wic: mount /boot and exlude it from root for efi
  meta-isar: use "systemd-boot" for one test target
