We really have a mess of extern/non-extern declaration
of functions in our headers. Always use extern for
unification purpose.

We are going to replace pid on id in names of image files. The id is
uniq for each namespace, so it's more convient, if image files are
opened per namespace.

We have generic do_pb_show() call and tons of show_foo
routines, that just call one with proper args. Compact
the code by putting the args into array and calling
the do_pb_show() in one place.

TUN devices are created with ioctl, but their parameters (e.g.
flags with state, mtu, etc.) are to be restored with generic
RTM_SETLINK message.

Some (most) network devices would like to have NetDeviceEntry with
more fields, than currently present (and enough for lo and veth).
Prepare for that by allowing them to define their own callback that
would fill the resor of the pb entry and call write_netdev_img().

These are structs that (now) tie together ns string
and the CLONE_ flag. It's nice to have one (some code
becomes simpler) and will help us with auto-namespaces
detection.

It will be required to support socket bound to devices.
When restoring w/o net namespaces -- collect existing devices.
When restoring with them -- collect what is received from image.

When restoring a container crtools create veth pair inside it and then
pushed one end to the namespaces crtools live in (outside). To facilitate
the subsequent management of the otter end of the veth pair this option
is added -- one can specifu a name by which the respective end would be
visible. E.g.: --veth-pair eth0=veth101.0

If an image isn't specified, crtool shows content of all images.
Now crtools aborts in this case due to BUG_ON(1) in show methods
for raw images. I sugget to skip such images.

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.
