Rework reboot/shutdown/poweroff/halt command

The provided utilities did not support all cases in which reboot and similar
utilities needs to support, ie.
 - running when dbus service is not running (eg. in upgrade target)
 - being invoked from vip handler when system must reboot immediately

This commit drops deviced custom tools - systemd native tools should be used
instead.

To ensure deviced is used during shutdown following is added:

 - deviced-request-shutdown utility and related service files

   These are installed as dependencies of systemd-standard shutdown
   procedure, causing these to be pulled automatically.

   Separate utility is added as, eg. dbus-send might not be available on
   production images.

 - /run/systemd/reboot-param handling is added

   This file is written by standard systemd reboot tool, so we need to both
   + read this file for reboot param in deviced-shutdown (needed if deviced was not used during shutdown)
   + read this file for deviced PowerOff argument (needed for normal operation)

Fix infinite recursive call for AOD corner case

 The subroutine triggered by lcd_off_procedure() could lead infinite
recursive call. This can happen when the lcd_off_procedure() do not
serve actual DPMS_OFF, remaining display state as DPMS_ON even after
the call.
One of the case is when the clockend signal arrives late. In this
situation, deviced forces to set ambient_state as false, but actual node
of lcd power remains ON. This combination of two state* makes deviced
perceive dpms state as DPMS_ON. As a result, lcd_off_procedure() has
been processed, but deviced still recognize dpms state as DPMS_ON,
triggering recursive call for lcd_off_procedure() to turning off display.
 [*] ambient_state=>false && lcd node=>ON

Possible callstack of recursive call
 del_state_cond
 -> default_trans

 -> lcd_off_procedure**
 -> ambient_set_state(true)
 -> pm_lock_internal
 -> proc_condition
 -> proc_condition_lock
 -> proc_change_state
 -> lcd_off_procedure [repeat **]

To fix this, leave ambient_state as it is when clockend arrival is
delayed. This makes deviced perceive DPMS state as DPMS_OFF, and it
won't trigger lcd_off_procedure().

Manage application state: foreground, background, terminated

Foreground / Background
  An application's lock is managed more strictly from the point when the
  application requires it. Now determine the memeber variable 'background'
  of PmLockNode based on the application's fg/bg state when adding lock
  as a new PmLockNode.

Terminated
  When an application is terminated without releasing lock, deviced unlocks
  it right away. At the same time, deviced decides whether to change state
  or not. At before, for this situation, it was responsible
  for pmlock_check() to release lingering lock of terminated application.
