When restoring venet device we need to restore its
index as well, which actually possible with new iproute2
package but the problem is that the index itself lays
inside image file. We could use crit tool to extract
it but this would slowdon procedure signifantly (need
to run python which would parse the image, or need
to pass the index into environmnet from inside of
the CRIU itself).
So lets do a trick and simply created venet device
inside container by criu itself (thanks we support
creating venet via netlink interface now).

This kind of netdevice will serve for external
links such as venet, macvlan/vlan and etc.

There will be two entities handled:
1. tun file -- an opened char device with misc major and tun minor
that can be attached to item #2
2. tun netdevice -- another type of links

These devices can be distinguished by type ETHER and kind "veth".
Some problems with peer detection exists (described in comment), but
we cannot handle them at the moment.

Only support the lo device. This is not final yet (much more
stuff is to be handled for a link) but is rather a skeleton
showing how to do it and letting us check the LXC container
early.
