This patch introduces VHOST_USER_PROTOCOL_F_HOST_NOTIFIER.
With this feature negotiated, vhost-user backend can register
memory region based host notifiers. And it will allow the guest
driver in the VM to notify the hardware accelerator at the
vhost-user backend directly.

When multi queue is enabled e.g. for a virtio-net device,
each queue pair will have a vhost_dev, and the only thing
shared between vhost devs currently is the chardev. This
patch introduces a vhost-user state structure which will
be shared by all vhost devs of the same virtio device.
