Fix runlevel switching; handle powerfail commands.

* src/ctl.c (prog_serialize): List runlevels.
* src/pies.c (main): Set got_alarm after reloading configuration.
Handle ACTION_POWER.
* src/pies.h (ACTION_POWER): New constant.
(progman_running_p): Rename to progman_waiting_p. All uses changed.
(sysvinit_power): New proto.
(POWER_STAT_FILE): New define.
(POWER_STAT_FAIL,POWER_STAT_LOW,POWER_STAT_OK): New constants.
* src/prog.h (prog) <idx>: Remove.
(prog) <wait>: New member.
* src/progman.c (prog_lookup_by_idx): Remove.
(progman_waiting_p): Return 1 only if there is at least one
prog with v.p.wait set.
(prog_start): Initialize v.p.wait for sysvinit components.
(progman_start): Don't do anything if waiting for components from
the previous runlevel.
(progman_wake_sleeping): Likewise.
(progman_cleanup): Assume expect_term if waiting for components from
the previous runlevel.
Clear v.p.wait on exited progs.
* src/sysvinit.c (sysvinit_fifo_handler): Don't call progman_stop
when handling runlevel changes.
Handle INIT_CMD_POWERFAIL, INIT_CMD_POWERFAILNOW, and
INIT_CMD_POWEROK.
(sysvinit_sigtrans): Handle SIGPWR.
(is_comp_wait): Rewrite.
(power_stat_file): New variable.
