These are components that are run at program startup. Starting
other components is delayed until all startup components terminate.
This is similar to SysV "bootwait" components.
Upon termination, startup components are removed from the configuration.
They are not renewed upon configuratuion reload.
* src/comp.c (comp_array_remove): Remove from the depmap as well.
(component_ref_decr): Use comp_array_remove for active components
and plain component_free for inactive ones.
(component_build_depmap): Use comp_array_remove.
(component_config_commit): Special handling for pies_comp_startup
components.
* src/pies.c (modetab): New component modes: "startup" and "shutdown".
(main): Run program_init_startup.
* src/pies.h (pies_comp_mode): New modes: pies_comp_startup and
pies_comp_shutdown.
(program_init_startup): New proto.
* src/progman.c (progman_waiting_p): Return 1 if a startup component
is still running.
(program_init_startup): New function.
(progman_cleanup): Handle pies_comp_startup termination.
* src/socket.c (switch_eids): Avoid unnecessary calls to setegid
and seteuid.
* tests/atlocal.in (auxdir): New variable.
* tests/mailer: Move to tests/aux/
* tests/respawn: Move to tests/aux/
* tests/retcode: Move to tests/aux/
* tests/aux/startup: New auxiliary program.
* tests/redirect.at: Start components from $auxdir.
* tests/respawn.at: Likewise.
* tests/ret-exec.at: Likewise.
* tests/ret-notify.at: Likewise.
* tests/startup.at: New file.
* tests/testsuite.at: Include startup.at
* tests/Makefile.am: Add new tests.

State transition algorithm used this far could cause spurious component
wakeups in some cases. Consider the following scenario: being in
runlevel N, the configuration is changed so that a component X is added
at runlevel N. Then a change to runlevel N+1 is initiated. What happens
then is that X is woken up (still being in runlevel N) and terminated
shortly afterwards, upon entering runlevel N+1.
To avoid this, configuration must be reloaded after runlevel changes.
* src/ctl.c (res_runlevel): Don't initiate ACTION_RELOAD after
setting the runlevel.
* src/pies.c (main): Begin main event loop with call
to pies_pause.
* src/pies.h (pies_set_hook): New proto.
(inittrans): Remove proto.
* src/socket.c (pies_set_hook): New function.
(pies_pause): Call pies_pause_hook if defined.
* src/sysvinit.c (inittrans): Change to static.
If transition was initiated by user (e.g. by invoking telinit),
schedule ACTION_RELOAD.
(sysvinit_begin): Set inittrans as pies_hook
