The octasic library is relatively large and is currently separately linked into
both the wcte13xp and wct4xxp libraries. This change moves it out into a
separate loadable module.
The bigest change from the drivers perspectives is that they must provide a
table of callbacks instead of using statically linked Oct6100UserXxxxx functions
to allow the library to communicate with actual parts on the cards.
