Update functional memory to have a response event

Clean out old memory python files, move them into old_mem directory.  Maybe we should just delete them, they are under revision control.

Add new py files for new objects.

SConscript:
    Update because memory is just a header file now
base/chunk_generator.hh:
    Make Chunk Generator return the entire size if the chunk_size is set to zero.  Useful when trying to chunck on blocksize of memory, which can write large pieces of data.
cpu/simple/cpu.cc:
    Make sure to delete the pkt.
mem/physical.cc:
mem/physical.hh:
    Set up response event.
mem/port.cc:
    Rename rqst to req to conform to same standard naming convention.
python/m5/objects/PhysicalMemory.py:
    Update the params, inheritence
