This optimization was once used in qemu-kvm to keep KVM route usage low.
But now we solved that problem via lazy updates. It also tried to handle

However, this never really worked and will have to be addressed
differently anyw

This is part 1 of a three-part series that expands usage of EventNotifier

EventNotifier right now cannot be used as an inter-thread communication
primitive. It only works if something else (the kernel) sets the eventfd.
Add a primitive to signal an EventNotifier that another thread is waiting
on.

Under Win32, EventNotifiers will not have event_notifier_get_fd, so we
cannot call it in common code such as hw/virtio-pci.c. Pass a pointer to
the notifier, and only retrieve the file descriptor in kvm-specific code.

All transports can use the same event handler for the ioeventfd, though
the exact setup (address/memory region) will be specific.
This lets virtio use event_notifier_set_handler.

All of ivshmem's usage of eventfd now has a corresponding API in
EventNotifier. Simplify the code by using it, and also use the
memory API consistently to set up and tear down the ioeventfds.

Win32 event notifiers are not file descriptors, so they will not be able
to use qemu_set_fd_handler. But even if for now we only have a POSIX
version of EventNotifier, we can add a specific function that wraps
the call.
The wrapper passes the EventNotifier as the opaque value so that it will

This is broken; since the eventfd is used in nonblocking mode there
is a race between reading and writing.

All transports can use the same event handler for the irqfd, though the
exact mechanics of the assignment will be specific. Note that there
are three states: handled by the kernel, handled in userspace, disabled.
This also lets virtio use event_notifier_set_handler.
