This patch introduces a new flag ATTR_KEY for hotplugged input devices, so we can better distinguish between real keyboards (i.e. devices with udev property ID_INPUT_KEYBOARD="1") and other key input devices like lid switches, power buttons, etc. All supported hotplug backends (udev, hal, and wscons) will set both flags ATTR_KEY and ATTR_KEYBOARD for real keyboards, but udev backend will set ATTR_KEY, but not ATTR_KEYBOARD, for non-keyboard key input devices (hal and wscons will set both flags in any case). With this distinction, kdrive input hotplugging mechanism will be allowed to only grab real keyboards, as other key input devices are currently not supported. In order to don't break current behaviour, this patch will replace all ATTR_KEYBOARD occurrences with ATTR_KEY in hw/xfree86/common/xf86Xinput.c.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
