This new API can be used to retrieve the type of a specific interface.
It's mostly platform dependant, but right now expected values are
"ovpn-dco", "tun" or "tap".
Other values are possible too, but they are not of interest to us.
This commit also extends the networking unit-test by using the newly
introduced API in conjunction with iface_new and iface_del.
The t_net.sh script has been slightly adapted to allow running these
tests in standalone (as they don't require any iproute2 counterpart).

A dummy interface cannot be deleted using --rmtun because openvpn tries
to send some ioctl (i.e. TUNSETPERSIST) which is not supported by this
device type. This results in the following error:
2022-04-07 09:59:29 Cannot ioctl TUNSETPERSIST(0) ovpn-dummy0: Bad file
descriptor (errno=9)
2022-04-07 09:59:29 Exiting due to fatal error
and the interface is not deleted.
Use iproute to generically delete an interface.

dummy0 gives strange errors on the Ubuntu 16 runner on github actions
because
dummy already exist, so use a more unique ovpn-dummy0 name instead.
Github actions are a good alternative to travis-ci, which futrure is
questionable
at the moment without payment. The github actions also allows building on
macOS
and Windows (not included in this commit). The matrix is a bit different
than Coverity and uses different Ubuntu version with their native OpenSSL
(1.0.2, 1.1.1)/mbed TLS instead of manually compiling different OpenSSL
versions on just Ubuntu 20.04.

Right now t_net.sh depends on t_client.rc in order to source the
RUN_SUDO variable only.
However, t_client.rc is something that a few people only have configured
and thus this would result in t_net.sh almost never executed even if it
just could.
Drop dependency on t_client.rc by falling back to RUN_SUDO=sudo when the
file is missing and no RUN_SUDO is passed via env.
While at it, reword the error message to better match the current logic
flow.

The tun interface has proved to be a bit fragile for basic netlink tests
as it may introduce delays in switching state, depending on the system
the test is ran on.
For this reason, switch to dummy interface type and at the same type
set its oper-state to up right after creation to avoid hitting the
no-carrier state later. No-carrier has been problematic in pasts tests
as it sometimes persists long enough to create a discrepancy between the
various tests snapshots thus causing a test failure.
Setting a static MAC addressis also re-enabled to avoid it being
different and thus causing a test failure when comparing snapshots.

Interfaces of type tun are marked as NO-CARRIER when no process is
attached to them. However, this bit gets set with some delay after
creation.
For this reason, it is better to wait for the bit to settle before
starting any test, otherwise any timing influence on the test may lead
to inconsistencies due to the NO-CARRIER bit randomly being or not in
the snapshot output taken by t_net.sh.
This patch add a 'sleep 1' command right after creation of the
interface, to give the NO-CARRIER bit a chance to settle.
This issue has been witnessed on a buildbot that is
apparently slowler than average to run the unit tests.

1) Building the networking unit-test when SITNL is not enabled does not
make much sense right now.
Make compilation dependent on having SITNL configured.
2) Remove some no-op mock_msg function calls.
3) Remove obsolete comment and declarations

The current script is performing a test on the "kill" command, but this
is not useful to the t_net.sh script as it never really executes it.
Rather test that "sudo <unit-test-binary>" really works.
<unit-test-binary> has to be added to the sudoers file if this test
has to be performend unattanded. The path is:
./unit_tests/openvpn/networking_testdriver
On top of that, print a simple OK for every test that is succesful.

The t_net script currently has #!/bin/sh but it implicitly assume to
be using bash.
This is fine on most distros, but some do not have sh pointing to bash
by default, thus breaking the script.
Explicitly use bash to avoid failures.
On the other hand, run this unit-test only if SITNL was enabled at
compile time. This test was designed with SITNL in mind and it is
not yet ready for other backends.
Running only when SITNL is enabled implies running on Linux only
therefore we are guaranteed that bash will always work.
While at it, also add a comment as of why the t_client.rc file is
sourced.

This patch introduces a new unit test that is not executed
by the cmocka framework, but rather used by a new t_net.sh
bash script.
The idea behind this test is to ensure that invoking sitnl
functions or running iproute commands leads to the same
networking (interface and routing table) state.
To achieve this, the t_net.sh script first runs a binary
implemented invoking sitnl functions and then takes a
"screenshot" of the state. Subsequently a series of
iproute commands, expected to mimic exactly the same behaviour
as the sitnl functions invoked before, are executed.
The final state is then compared with the screenshot
previously taken.
If no mismatching is found, the test is passed.
The current unit_test, however, does not cover all the
sitnl functionalities and it is expected to be extended
in the future.
