9118effd1b 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.

7e5fcb0b34 xen: add elfnote.h to avoid using numbers instead of constants
Various features and parameters of a pv-kernel are specified via
elf notes in the kernel image. Those notes are part of the interface
between the Xen hypervisor and the kernel.

Instead of using num,bers in the code when interpreting the elf notes
make use of the header supplied by Xen for that purpose.
