Bastien Nocera 01a0fa9437 idle-monitor: Add ResetIdletime API, for testing purposes
The ResetIdletime API can be used instead of an "XTest" binary to
programmatically reset the idle time, as if the user pressed a button on
a keyboard.

This is necessary since we stopped using the XSync extension to monitor
idletimes, as it didn't consider inhibitors as busy, and mutter's
clutter code ignores "Core Events" as generated by XTest.

This patch will require minimal changes to gnome-settings-daemon's power
test suite so that "key press" idletime resets are triggered through
this D-Bus interface rather than through XTest and a roundtrip through
the X server.
