PATCH 1/3 Add systemd units for dmeventd and lvm2 monitoring

These units are already being used and tested in Fedora rawhide directly:

dm_event_systemd_red_hat.service.in (dm-event.service) dm_event_systemd_red_hat.socket (dm-event.socket) lvm2_monitoring_systemd_red_hat.service.in (lvm2-monitor.service)

I'm just resending them here for any additional comments (I've just added the OOMScoreAdjust to dm-event.service and SocketMode to dm-event.socket when compared to rawhide).

Note: Conflicts: shutdown.target will stop monitoring before unmounting any mounted filesystems. But this is as far as we can go now. Monitor deactivation should be done later, but that will be handled properly if we have shutdown ramfs in place (which is also planned, at least for Fedora 16).

Peter
