Add service configuration reloading
...
This commit add the ability to initd to reload the service configuration
while running. The new configuration is merged with the existing one as
follows:
For each target:
- If the existing service list is not NULL, we have not started that
target yet. Simply replace it with the new list.
- If it is NULL, the services have already been started.
- First, remove all entries for services in that target that no
loner exist (except from the 'running' list).
- Second, add new services that we don't have yet. Treat them as
recently diseased and let the user start them manualy.

Add helper program for running services
...
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.
