This is all merged on master. I've created a 0.9 branch before that for
your backporting leisure.

This is implemented. It depends on a new property called "WarningLevel"
on the devices and the daemon itself.

This was implemented and merged for keyboard backlight. systemd 107
already had the feature for display backlights.

There's "WarningLevel" for devices and the daemon, and I've added
"IconName" for each of the devices.
