evdev: Add hotplugging support

This adds hotplugging support to the evdev input backend. We use
libudev to monitor changes to input devices in a separate thread.
Removed devices are removed from the devices list, and new devices
are added to the list.

The effect is that controllers are usable immediately after plugging
them without having to manually refresh devices (if they were
configured to be used, of course).
