Ron Dreslinski 4fff6d4603 Fixes to cache eliminating the assumption that the Packet is still valid after sending out a request.
Still need to rework upgrades into this system, but works for now.

src/mem/cache/base_cache.cc:
    Re order code to be more readable
src/mem/cache/base_cache.hh:
    Be sure to delete the copy on a bus block
src/mem/cache/cache_impl.hh:
    Be sure to remove the copy on a writeback success
src/mem/cache/miss/mshr_queue.cc:
    Demorgans to make it easier to understand
src/mem/tport.cc:
    Delete writebacks

Ali Saidi 3d2764acf3 replace functional code in tport with fixPacket().
fixPacket() should be used anywhere a functional packet and timing packet are found to have the same address.

Ron Dreslinski f89b56b61a Check the response queue on functional accesses.
The response queue is not tying up an MSHR, should we change that or assume infinite storage for responses?

src/mem/cache/base_cache.cc:
src/mem/tport.cc:
    Add in functional check of retry queued packets.
