Any input device with this option will be automatically added to whichever
server layout is selected at startup. This removes the need to reference a
device from the ServerLayout section. The two following configuration are
identical:

CONFIG 1:
    Section "ServerLayout"
            InputDevice "foo"
    EndSection

    Section "InputDevice"
            Identifier "foo"
            ...
    EndSection

CONFIG 2:
    Section "InputDevice"
            Identifier "foo"
            Option "AutoServerLayout" "on"
            ...
    EndSection

The selection of the server layout affects both explicitly specified
layouts and the implicit layout.
