Suspend on lid close based on power status. (#8016)

This change adds support for controlling the suspend-on-lid-close
behaviour based on the power status as well as whether the machine is
docked or has an external monitor. For backwards compatibility the new
configuration file variable is ignored completely by default, and must
be set explicitly before being considered in any decisions.
