Martin Gräßlin 6a032e78b7 Suspend/Resume libinput when logind session Active changes
LogindIntegration starts monitoring the Active property on the session
and emits a signal when the state changes. The LibInput::Connection
connects to this signal during the setup and uses it to suspend/resume
the libinput context.
