PPOS update
Added the capability structures for all the major data-structures, and the liveness map.

Right now, they are all in platform/tests/ppos/ for the most part, and
the shell of most of the capcap operations will be implemented there.
For now, we want to get the data-structures right, and iterate from
there.
NOT WORKING, but have to go to Germany...have fun Qi
