Not entirely true, being at the beginning of the struct is already

If you look at the patchset you will find that it was not properly

This optimization was once used in qemu-kvm to keep KVM route usage low.
But now we solved that problem via lazy updates.
What if we are using vhost which AFAIK can't use the lazy path?

For some examples:
1. client calls 'add-fd', qemu is now tracking fd=4 with refcount 1, in
use by monitor, as member of fdset1
2. client crashes, so all tracked fds are visited; fd=4 had not yet been
passed to 'remove-fd', so qemu decrements

This is part 1 of a three-part series that expands usage of EventNotifier
in QEMU (including AIO and the main loop). I started working on this when
playing with the threaded block layer; the part of that work that I hope
will be in 1.2 is generalizing posix-aio-compat.c to be a generic portable
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.
