Franck Bui aed24c4cd7 logind: save/restore session devices and their respective file descriptors
This patch ensures that session devices are saved for each session.

In order to make the revokation logic work when logind is restarted, the
session devices are now saved in the session state files and their respective
file descriptors sent to PID1's fdstore in order to keep them open accross
restart.

This is mandatory in order to keep the revokation logic working. Indeed in case
of input-devices, the same file descriptors must be shared by logind and a
given session controller in order EVIOCREVOKE to work otherwise multiple
sessions can have device access in parallel.

This should be the only remaining and missing piece for making logind fully
restartable.
