[PATCH xserver] xfree86: add support for MatchIsTabletPad

[Peter Hutterer]

The tablet pads have been separate kernel devices for a while now and
libwacom has labelled them with the udev ID_INPUT_TABLET_PAD for over a year
now. Add a new MatchIsTabletPad directive to apply configuration options
specifically to the Pad part of a tablet.
