xen/include: define new handle param

During domU creation process the colors selection has to be passed to
the Xen hypercall. This selection is defined as an array. We need thus
to pass the pointer to Xen and make it accessible in its memory space.
This is generally done using what Xen calls GUEST_HANDLE_PARAMS. Add a
new parameter that allows us to pass both the colors array and the
number of elements in it.
