At this point in the code, the acked features have been provided by the
guest and they can be set back to the backend. There's no need to
retrieve one more time the backend features for this purpose.

As mentioned in the vhost-user specification, each ring is initialized
in a stopped state. This means each ring should be enabled only after
it has been correctly initialized.

The available features are masked with the backend features, therefore
the available features should be the one used when calling into
set_features() API.

In order to factorize the code between vhost-user-net and virtio-fs one
step further, this patch extends the vhost-user handler implementation
to support slave requests.

This patch factorizes the existing virtio-fs code by relying onto the
common code part of the vhost_user module in the vm-virtio crate.
In details, it factorizes the vhost-user setup, and reuses the error
types defined by the module instead of defining its own types.

vhost-user-net introduced a new module vhost_user inside the vm-virtio
crate. Because virtio-fs is actually vhost-user-fs, it belongs to this
new module and needs to be moved there.

vhost-user framwork could provide good performance in data intensive
scenario due to the memory sharing mechanism. Implement vhost-user-net
device to get the benefit for Rust-based VMMs network.
