7de12ae764 networkd-wait-online: track links
Rather than refetching the link information on ever event, we liston to
rtnl to track them. Much code stolen from resolved.

This will allow us to simplify the sd-network api and don't expose
information available over rtnl.

0014a4ad50 sd-network: fix parameter order for sd_network_monitor_new()
Constructors should return the object they created as first parameter,
except when they are generated as a child/member object of some other
object in which case that should be first.

Otherwise the event will trigger immediately again.

27134b2f05 networkd-wait-online: refactor a bit
Clarify that we are waiting for any link to reach 'carrier' state, regardless
of who manages it. This will be useful when we add support for waiting for more
operational states.

3a67e927e3 networkd-wait-online: improve interoptability and enable by default
To make sure we don't delay boot on systems where (some) network links are managed by someone else
we don't block if something else has successfully brought up a link.

We will still block until all links we are aware of that are  managed by networkd have been
configured, but if no such links exist, and someone else have configured a link sufficiently
that it has a carrier, it may be that the link is ready so we should no longer block.

Note that in all likelyhood the link is not ready (no addresses/routes configured),
so whatever network managment daemon configured it should provide a similar wait-online
service to block network-online.target until it is ready.

The aim is to block as long as we know networking is not fully configured, but no longer. This
will allow systemd-networkd-wait-online.service to be enabled on any system, even if we don't
know whether networkd is the main/only network manager.

Even in the case networking is fully configured by networkd, the default behavior may not be
sufficient: if two links need to be configured, but the first is fully configured before the
second one appears we will assume the network is up. To work around that, we allow specifying
specific devices to wait for before considering the network up.

This unit is enabled by default, just like systemd-networkd, but will only be pulled in if
anyone pulls in network-online.target.

020d59000f networkd: add networkd-wait-online
This is mostly a proof of concept to try sd-network, so we don't
hook it up with a .service file quite yet. We probably want it to
be more clever about deciding when we are 'online'.

The binary  will wait for at least one network managed by networkd,
and until all networks managed by networkd are configured.
