028394b8a5 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.

e21840cfce initd: don't start runsvc for services without exec block 
First in rdsvc, tag the services that *do* have exec lines, even if we don't
read them.

Second, if a service does not have that flag set, don't try to execute it.

390175c406 cleanup runsvc: merge codepaths for execution, remove cleanup code 
Simply execute the last entry in the list directly instead of forking and
remove the cleanup code.

If the list is empty, we return success.

If the list only has one entry, we directly execute that. No need to make a
distinction between single entry vs list anymore.

If the list is an actual list, we run it as before but execute the last one
directly. Typically, the last one is something like a daemon preceeded by
setup code. The daemon ends up directly underneath init, without a dummy
waiting runsvc stuck in the process list.

If we always do an exec, there is no point in doing cleanup. All our mapped
memory is evicted anyway. Same if we exit appruptly because of an error.
