This patch adds a first Infix model to augment ietf-ip with a node,
similar to the IPv6 'autoconf' node, also for IPv4. For IPv6 the
autoconf feature comes built-in, for IPv4 it is defined in RFC3927.
The setting behaves the same as for IPv6, but in the case of IPv4 we
enable avahi-autoipd per interface to acquire the 169.254/16 address.

With the new templating support in Finit, and this patch, we can now
very easily enable a ZeroConf service on, e.g., eth0:
$ initctl enable zeroconf@eth0

The root user is by default not allowed to log in over SSH, so we add an
admin user with limited root privileges for this purpose.

When calling 'make skeleton-init-finit-rebuild' to (re)install any new
or modified services, we cannot remove everything installed already.
That breaks what other packages may have installed already and is not
the Buildroot way.

The init_next_gen() function moves us to the next generation, as well as
intialize all data files for expected interfaces in that generation.
However, bridge and lag interfaces have dependendcies that need to be
moved as well. It is only the test author that knows the expected new
state, so this function only sets up the desired state, without ever
looking at what any previous generation looked like.

With more advanced interface types we cannot use create_iface() to set
up the file structure in new generations. This commit adds a _data()
function that should be used instead.

The net tool traverses the graph and executes the scripts et al in
postorder, i.e., all leaves are evaluated first before the parent's
script is run. Hence, attaching ports to a bridge or link aggregate
is the responsibility of the parent, not the leaves.

For instance, when adding ip command to the ip pipe we need the kernel
to execute those commands before the bridge command pipe is executed.

Host tools and target are often out of sync, sometimes because we need
to run a newer version of iproute2 with more features. By installing
tests to target we can still verify basic functionality, provided the
tests verify their dependencies and exit 77 (SKIP).

- Simplify build process, including cross compilation
- Add basic test framework, available as `make check`

Run with unshare, as so:
make clean; make; cd test/
unshare -mrun ./three-independent.sh
This sets up a test directory in /tmp/net, creates three independtent
interface configs for dummy interfaces. Activates the config with a
call to `net -vd apply`, and then verifies the result using a mix of
ip link/addr and jq magic.

Calling net prevsiouly meant `net do`, the new separation is to be able
to add `net up` and `net down` commands, with optional interface args.
The idea is to support the same semantics as `ifup -a` of `ifup foo`.

Naming the actions after their executing entity, e.g., foo.sh when it is
executed by /bin/sh, is a tried and true paradigm.

When taking down a network setup, it needs to be deconstructed using the
foo.exit rules of the previous generation, and in reverse dependency
order.
This patch adds support for generating the deps when bringing up the
network setup, and saving an rdeps file in that generation, which can
be used later when moving leafs between nodes.
