This adds support for emulating Xen under Linux/KVM, based on kernel
patches which have been present since Linux v5.12. As with the kernel
support, it's derived from work started by João Martins of Oracle in
2018.
This series just adds the basic platform support — CPUID, hypercalls,
event channels, a stub of XenStore.
A full single-tenant internal implementation of XenStore, and patches
to make QEMU's Xen PV drivers work with this Xen emulation, are waiting
in the wings to be submitted in a follow-on patch series.
As noted in the documentation, it's enabled by setting the xen-version
property on the KVM accelerator, e.g.:
qemu-system-x86_64 -serial mon:stdio -M q35 -display none -m 1G -smp 2 \
-accel kvm,xen-version=0x4000e,kernel-irqchip=split \
-kernel vmlinuz-6.0.7-301.fc37.x86_64 \
-append "console=ttyS0 root=/dev/sda1" \
-drive file=/var/lib/libvirt/images/fedora28.qcow2,if=none,id=disk \
-device ahci,id=ahci -device ide-hd,drive=disk,bus=ahci.0
Even before this was merged, we've already been using it to find and fix
bugs in the Linux kernel Xen guest support:

To avoid lots of copy and paste lets deal with artefacts in a
template. This way we can filter out most of the pre-binary object and
library files we no longer need as we have the final binaries.
build-system-alpine also saved .git-submodule-status so for simplicity
we bring that into the template as well.
As an example the build-system-ubuntu artefacts before this patch
where around 1.3 GB, after dropping the object files it comes to 970
MB.
