Subject: [PATCH 1003/1003] logind: store a timestamp when the ACPI power
 button is pressed

When we get a D-Bus call to shutdown, we'll use the corresponding
timestamp to see if this call is due to GDM responding to the ACPI
power button itself, or just due to any random program calling the
D-Bus shutdown method.

[federico: fixes bsc#888612]
[fbui: fixes bsc#1072933]
