Tobias WaldekranzandJoachim Wiberg 2259e108e4 confd: Rename srx_set_item -> lydx_new_path 
Since this function wraps lyd_new_path.

This allows us to write a wrapper for sr_set_item, using the expected
name.

Joachim WibergandTobias Waldekranz 64804bee5d src/net: add missing deps when moving between generations 
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.

function that should be used instead.

Joachim WibergandTobias Waldekranz 7945207989 src/net: fix interface creation/attach order in generation generator 
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.

Joachim WibergandTobias Waldekranz a26dd9c19f src/net: install tests to target /usr/share/net 
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).

Joachim WibergandTobias Waldekranz da56f8d653 src/net: first automated test case, run with unshare 
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`.

Joachim WibergandTobias Waldekranz 47c3448774 src/net: calculate and run teardown in reverse dependency order 
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.
