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.

and plain component_free for inactive ones.

(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.

is still running.

All ACL keywords can be used in simple statement as well as in block form.
As simple statements, they take a name of an already defined named ACL. E.g.:
defacl forbid {
deny any;
}
component foo {
list-acl forbid;
}
This commit also fixes some eventual double-frees.

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.

If transition was initiated by user (e.g. by invoking telinit),
schedule ACTION_RELOAD.
(sysvinit_begin): Set inittrans as pies_hook

are properly closed before being reopened by progman_create_sockets
