Refactoring of the OpenBIOS source code, as discussed on the mailing list. The primary aim of this process is to try and arrange

the source files into a structure whereby it is easier to find the relationship between a forth package word and its C 
implementation, while also creating a libopenbios library into which more common code from the arch/ tree can eventually be 
moved.
