Joachim Nilsson d21dc2b477 Westermo service starter and supervisor, inspired by daemontools
finit.c:
        o New service and shell_service stanzas for finit.conf
        o Run service_startup() before /etc/finit.d/ hooks
        o Run service_monitor() at end of startup

helpers.c:
        o Several new functions:
          - print_desc() displays a service starting up
          - print_result() shows if service started OK or not
          - start_process() is used by the services framework

svc.c:
        Generic API for managing svc_t structures

ipc.o:
        TIPC based framework for communicating with the service monitor.
        E.g., to relay (re)configuration signals from a Web/CLI
        front-end via finit to one or many setup daemons, and back.

services.c:
        Service monitor framework

strlcpy.c:
        Secure strncpy() replacement from OpenBSD under the free ISC License.
