Revamp program termination after reconfiguring.

* src/pies.h (PIES_CHLD_GC): New op.
(progman_stop_tag): Remove proto.
* src/pies.c (main): Handle PIES_CHLD_GC: stop all programs marked
for termination.
* src/comp.c (component_config_commit): Mark leftover components
for termination, instead of waiting for them to terminate.
* src/sysvinit.c (runlevel_setup_prog): Skip prog if its
active status didn't change.
Mark inactivated progs for termination.
(sysvinit_runlevel_setup): Schedule PIES_CHLD_GC.
(inittrans): Don't wait for programs to terminate. That will be done
in the main loop.
* src/prog.h (prog)<stop>: New boolean member.
* src/progman.c (progman_cleanup)
(progman_stop_component): Clear the stop flag.
(progman_gc): New function.
(progman_stop_tag): Remove.
