Fixes to get compiling to work. This is mainly fixing up some includes; changing functions within the XCs; changing MemReqPtrs to Requests or Packets where appropriate. Currently the O3 and Ozone CPUs do not work in the new memory system; I still need to fix up the ports to work and handle responses properly.
