logind: optionally handle power, sleep and lid switch events

This takes handling of chassis power and sleep keys as well as the lid
switch over from acpid.

This logic is enabled by default for power and sleep keys, but not for
the lid switch.

If a graphical session is in the foreground no action is taken under the
assumption that the graphical session does this.
