kvm: add KVM_IRQFD_FLAG_RESAMPLE support
Added an EventNotifier* parameter to
kvm-all.c:kvm_irqchip_add_irqfd_notifier(), in order to give KVM
another eventfd to be used as "resamplefd". See the documentation
in the linux kernel sources in Documentation/virtual/kvm/api.txt
(section 4.75) for more details.
When the added parameter is passed NULL, the behaviour of the
function is unchanged with respect to the previous versions.
