    kernel - Bring in evdev from FreeBSD
    
    * This is a port of evdev, the generic input event interface, from
      FreeBSD. Wikipedia: "Evdev generalizes raw input events from device
      drivers and makes them available through character devices in the
      /dev/input/ directory."
    
    * It is currently considered experimental since in rare cases it may cause
      kernel crash when a device, e.g. usb mouse or keyboard, is detached
      while a userland program reading from the corresponding input/eventX
      device.
    
    * In order to enable evdev, kernel needs to be rebuilt with 'device evdev'
      and 'options EVDEV_SUPPORT'. For debugging, add 'options EVDEV_DEBUG'.
    
    * At present, only ums, kbd and kbdmux can send events to their respective
      input/eventX devices. More drivers will be added in due course. The sysctl
      kern.evdev.rcpt_mask determines which drivers send events to evdev.
