40e4dc6339 vhost_user_backend: Change handle_event as immutable
By changing the mutability of this function, after adapting all
backends, we should be able to implement multithreads with
multiqueues support without hitting a bottleneck on the backend
locking.

8f434df1fb vhost_user: Adapt backends to let handle_event be immutable
Both blk, net and fs backends have been updated to avoid the requirement
of having handle_event(&mut self). This will allow the backend crate to
avoid taking a write lock onto the backend object, which will remove the
potential contention point when multiple threads will be handling
multiqueues.

700df9eb16 vhost_user_net: Port to new exit event strategy
Implement the exit_event() method on the VhostUserBackend trait. It is
necessary to specify a custom exit event id in this case as the loop is
also used for handling activity on the tap file descriptors.
