KVM: x86/xen: intercept EVTCHNOP_send from guests
Userspace registers a sending @port to either deliver to an @eventfd
or directly back to a local event channel port.
After binding events the guest or host may wish to bind those
events to a particular vcpu. This is usually done for unbound
and and interdomain events. Update requests are handled via the
KVM_XEN_EVTCHN_UPDATE flag.
Unregistered ports are handled by the emulator.
