Some systems don't have a hardware real time clock and don't know the time
after bootin. An obvious soulution for this is to use time from an ntp
server. Unfortunately that requires domain name resolution, which resolvers
like unbound won't do for us, if the DNSSEC certificates aren't valid, which
they aren't if we start out with a time around 1970-1-1.
The "software clock" service tries to provide a workaround by restoring a
reasonably valid time from a backup file during boot, which we update when
shuting down. If we wan't a more correct time, we have to update it from
NTP in between.

Add a service file and helper script to shut down all network interfaces
during shutdown or reboot.

For now this daemon simply dumps all syslog messages into seperate log
files and doesn't do much parsing. Since the messages are readable ASCII
anyway, this should not be to much of a problem and sufficient for
debugging.

After interface renaming is done, perform the following actions:
- Configure each interface for which we have a configuration file
- Configuration file contains lines that we pass directly to iproute2
- Configure static routing in a similar fashion
- Set the configured interfaces up

Add a new service that runs a small helper script that applies a consistent,
deterministic naming pattern to all interfaces, based on their mac address.
A configuration file with wild card pattern matching can be used for
determining names. By default, this is disabled.
Also, this script is Linux specific.

We no longer need to keep entire scripts in init program (i.e. saving space)
and reduce the code and complexity of the init program.
The runsvc tool can later be extended to do more complex child setup, such
as configuring namespaces or seccomp without adding complexity or memory
footprint to init.

- Common function for splitting string into argument vector
- Preprocess & split command lines while parsing the service file
- Specify "before" and "after" dependencies in a single line
