xen: features and fixes for 4.10 rc0

These are some fixes, a move of some arm related headers to share them
between arm and arm64 and a series introducing a helper to make code
more readable.

The most notable change is David stepping down as maintainer of the Xen
hypervisor interface. This results in me sending you the pull requests
for Xen related code from now on.

Thanks.

Juergen
