[libvirt] [PATCH libvirt 2/4] events: remove libxlDomainEventQueue wrapper func

[Anya Harter]

And replace all calls with virObjectEventStateQueue such that:

    libxlDomainEventQueue(driver, event);

becomes:

    virObjectEventStateQueue(driver->domainEventState, event);

And remove NULL checking from all callers.
