KVM: x86/xen: handle PV timers oneshot mode
If the guest has offloaded the timer virq, handle the following
hypercalls for programming the timer:
VCPUOP_set_singleshot_timer
VCPUOP_stop_singleshot_timer
set_timer_op(timestamp_ns)
The event channel corresponding to the timer virq is then used to inject
events once timer deadlines are met. For now we back the PV timer with
hrtimer.
[ dwmw2: Add save/restore, 32-bit compat mode, immediate delivery,
don't check timer in kvm_vcpu_has_event() ]
