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.
