[XEN,0/8] xen: Kconfig update with few extra

Message

Patch series available in this git branch:
https://xenbits.xen.org/git-http/people/aperard/xen-unstable.git br.build-system-xen-kconfig-v1

Hi,

This is a update of Kconfig as used to build the hypervisor. This is also in
preparation of using Kbuild. The first version of the series, with a POC of
using Kbuild to build xen can be found here:
https://lists.xenproject.org/archives/html/xen-devel/2019-10/msg01609.html

There's also some cleanup patches.

It has been suggested to me that Kconfig's new capability could be used to
generate CFLAGS. I'm not sure how, but I've already added some patches where
having CONFIG_* was already used.

New features of Kconfig:
    - Can run shell commands!
        This could be use to generate the CFLAGS and cleanup the Kconfig files
        to not have to depends on some env var (like XEN_HAS_BUILD_ID).
    - Update to the graphical menuconfig, xconfig. It's now built with Qt4/Qt5.
    - Probably others that I forgot.

This whole series should be "no functionality changes", I think.

Cheers,

Anthony PERARD (8):
