Revision 128

add tables support to LinuxBIOS. 

We have merged the plethora of include files into one. A given linuxbios
target architecture must support all the functions described therein. 
All the structs etc. in include/tables.h are known to be
architecture-independent. 

We hope this new layout is easier to folow than the old one. 

Todo: Remove the LGDT code from tables writing (how did THAT get in
there ;-) and put it somewhere sane; add OFW table support. We are going
to need some nice OFW table code. 

Also, the license headers should be correct in this commit.
