This should be longer, there are devices out there (in the industry)
that may drop the ball on a single ARP, or may be in deep sleep (IoT),
so we should send like 5 ARP with at least 1 sec between them before
timing out.
However, this requires patching BusyBox a bit, so skipping for now.

- Add support for option 12, provide current hostname to server for
registering the lease with -- this allows registering in local DNS
for some DHCP servers.
- Add support for option 50, request any previously cached IP address
- Override option 60, vendor class identifier, with Infix vYY.MM
- Adjust timers and retry options to be more persistant
- Include initial metric as environment variable to client
- Disable all default options, set a hard-coded subset, which will be
replaced in a later commit by a generated list.
- Ensure udhcpc creates a pid file, in case we may need to start any
other service/task in sync with the DHCP client

- New log() function replaces stdout logging
- New set_dhcp_routes() and clr_dhcp_routes() functions
- Set all option 121 routes with same metric
- Set all option 3 routers with increasing metric (this is what the
reference udhcpc scripts do, and RFC says the routers should be
listed in order of preference ...)
- Clearing routes must, like IP addresses, be done both by interface
and protocol. This refactor makes sure to delete any DHCP routes
set on the given interface (in case options change)
- Use resolvconf per-interface search+nameserver
- Cache IP lease so we can ask for it back later
- On deconfig|leasefail|nak, make sure to clean up anything that might
be lingering from this interface. E.g., we can get leasefail when a
server denies our request to prolong a lease.
- On renew|bound, refresh routes, and set search+dns + NTP servers

Move from everything in a single /etc/chrony.conf to a split up with
configuration and server snippets. The latter comes in the form of
configured (static) and DHCP client (dynamic) server setup.
To accomodate this new scheme we need to detect when serves are removed
from the configuration, so not only have the whole change_ntp() been
refactored, it has been extended with a new pass.

Break out unit tests to separate make target as they don't require all
the built code and infrastructure that the normal tests does.
Run the unit tests early in the Github action stage. They don't
require a full build. This will give early feedback to the users.

In this patch we add some arbitrary system output files which contains
interface data. Such as the output from "ip link" and "ethtool". These
files are used by yanger instead of running the actual commands.
Yanger then generates a lot of YANG json data, which are merged using
jq into something that looks like the sysrepo operational data on
a running system. This data is then passed though cli-pretty and its
ouput is compared to the static expected output in the .txt files in
cli-output.
Here's a basic flow overview.
* system-output/foo.json -> yanger ->> data
* system-output/bar.json -> yanger ->> data
* data -> merge -> sysrepo-operational-data
* sysrepo-operational-data -> cli-pretty -> output.txt
* compare output.txt too cli-output/show-foobar.txt
The result of this is that if something changes in yanger OR in
cli-pretty. The corresponding system-output file needs to be updated
for the test to pass. This is indented to catch regression where the
output is unintentionally changed.

Normally, no logins are actually possible, but this will have two
desirable effects effects:
- /etc/issue will be printed when hitting return over the console,
allowing the user to see the bootstrapping errors again, without
having to reboot the system.
- On devleoper builds, with CONFIG_TARGET_ENABLE_ROOT_LOGIN, we can
login as root and debug issues.
Collect all bootstrapping issues in all banner-like files during boot,
so that they are presented to the user when logging in. This should
make it harder to miss overlook the fact that a system is running in a
degraded state.
Before this change, the system would move to runlevel 9 as soon as
startup-config failed to load, in which no getty is allowed to run.
Instead, we want to reserve that runlevel for when failure-config
itself also fails to load, since the system will have no valid login
credentials at that point.
This fixes [ERR] from CLI `show routes`, and broken operational status
in setups with DHCP client enabled by default.
Feature (static routing) introduced in release cycle, no need to bring
up in release notes.

As it turns out, references to module objects are not safe to keep
across callbacks. In particular: loading a new model into sysrepo at
runtime may cause it to move objects around in memory.
Therefore, fetch a valid reference to "infix-system" on every callback
instead.
* sniffer did not work correctly
* links did not come upp as quick as in qemu
* must_reach in netns was to narrow, increase timeout
* add wait function to handle poll
Currently we only advertise SSH+SFTP services over mDNS-SD, which are
the default services from the avahi package. This patch adds support
for _netconf-ssh._tcp as well.
