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.
