Support sysvinit ondemand components.
* src/ctl.c (fun_start): Handle status_finished same as status_sleeping (for restarting ondemand components). * src/progman.c: Respawn ondemand components. * src/sysvinit.c (enablecomp): Handle pies_comp_ondemand. (sysvinit_demand): New function. (sysvinit_fifo_handler): Handle ondemand runlevels. (inittab_parse): Support "off" fields. Convert runlevels to upper case.
