Move NetQueuePair and the related NetCounters into the net_util crate.
This means that the vhost_user_net crate now no longer depends on
virtio-devices and so does not depend on the pci, qcow or other similar
crates. This significantly simplifies the build chain for this backend.

Remove the vmm dependency from vhost_user_block and vhost_user_net where
it was existing to use config::OptionParser. By moving the OptionParser
to its own crate at the top-level we can remove the very heavy
dependency that these vhost-user backends had.

The binary is still built in the same location but the source code and
the dependencies for it come from the vhost_user_net crate itself.
The binary will be built with:
`cargo build --all --bin vhost_user_net` or just `cargo build --all`

Split the generic virtio code (queues and device type) from the
VirtioDevice trait, transport and device implementations.
This also simplifies the feature handling in vhost_user_backend as the
vm-virtio crate is no longer has any features.

Switch to using the recently added OptionParser in the code that parses
the network backend.
Whilst doing this also update the net-backend syntax to use "sock"
rather than socket.

Extract the majority of the code that provides the vhost-user-net
backend into its own crate and port the binary to use it.
