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.
* doc/pies.texi: Update.

(pies_acl_use): New function.
(pies_acl_create): Initialize refcnt.

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/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

prog if it is a deactivated listener.

after mark stage, to ensure any eventual listener components
are properly closed before being reopened by progman_create_sockets
