This patch adds ARM support for guest-request monitor vm-events.
Note: on ARM hypercall instruction skipping must be done manually
by the caller. This will probably be changed in a future patch.

Summary of changes:
== Moved to common-side:
  * XEN_DOMCTL_MONITOR_EVENT_GUEST_REQUEST handling (moved from X86
      arch_monitor_domctl_event to common monitor_domctl)
  * hvm_event_guest_request->vm_event_monitor_guest_request
  * hvm_event_traps->vm_event_monitor_traps (also added target vcpu as param)
  * guest-request bits from X86 'struct arch_domain' (to common 'struct domain')
== ARM implementations:
  * do_hvm_op now handling of HVMOP_guest_request_vm_event => calls
      vm_event_monitor_guest_request (as on X86)
  * arch_monitor_get_capabilities->vm_event_monitor_get_capabilities,
    updated to reflect support for XEN_DOMCTL_MONITOR_EVENT_GUEST_REQUEST
  * vm_event_init_domain (does nothing), vm_event_cleanup_domain
== Misc:
  * vm_event_fill_regs, no longer X86-specific. ARM-side implementation of this
      function currently does nothing, that will be added in a separate patch.
