[XEN] Add a warning about changeable size of shared_info structure.

sizeof(shared_info_t) can change even in compatible hypervisor
versions.

In addition, add some padding to arch_shared_info, to allow future
additions to the structure without breaking known offsets of members
following it in the shared info.
