Fix #310: service restart delay not working

Browse Source 
Always use the configured restart delay for crashing services.  If no
delay is configured, we default to an initial 2000 msec for forking
daemons and start-stop scripts, and 1 msec for non-forking daemons.

We must track the increasing delay in the svc_t because processes can
fail quickly in differing ways.  E.g, the test daemon 'serv' behaves
extra evil by crashing right after having created its pidile (i.e.,
when it's signaled to Finit it is 'ready' and all is dandy ...).  If
we don't track the delay per svc_t we would restart 'serv' after only
1 msec every (other) time.
