Subject: [PATCH 01/20] xen: Add some Xen headers

In order to support grub2 in Xen PVH environment some additional Xen
headers are needed as grub2 will be started in PVH mode requiring to
use several HVM hypercalls and structures.

Add the needed headers from Xen 4.10 being the first Xen version with
full (not only experimental) PVH guest support.
