Add a support layer for the ISDN CAPI (http://www.capi.org/), which should 

make it pretty simple to write drivers for cards which conform to CAPI.

This code was originally written by Juha-Matti Liukkonen <jml@cubical.fi>
of Cubical Solutions Ltd. for FreeBSD, and was now adapted to NetBSD
by myself for the same company.
