Xen 4.16

[Jason Andryuk]

Hi,

I heard some talk of moving to Xen 4.15 late in 2021. Since then,
4.16 was released, so I moved my earlier 4.14 work forward to that.
You can see it here:
https://github.com/jandryuk/xenclient-oe/commits/xen-4.16
https://github.com/jandryuk/xsm-policy/commits/xen-4.16

You also need changes in these other 4.14 branches:
https://github.com/jandryuk/manager/commits/xen-4.14
https://gitlab.com/jandryuk/glass/-/commits/xen-4.14/
https://github.com/OpenXT/libxenbackend/pull/9

It's only been minimally tested.

Regards,
Jason
