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.  This check-in is so that the merge between m5 and newmem is no longer outstanding.

src/SConscript:
    Need to include FU Pool for new CPU model.  I'll try to figure out a cleaner way to handle this in the future.
src/base/traceflags.py:
    Include new traces flags, fix up merge mess up.
src/cpu/SConscript:
    Include the base_dyn_inst.cc as one of othe sources.
    Don't compile the Ozone CPU for now.
src/cpu/base.cc:
    Remove an extra } from the merge.
src/cpu/base_dyn_inst.cc:
    Fixes to make compiling work.  Don't instantiate the OzoneCPU for now.
