memory mode information now contained in system object

States are now running, draining, or drained. memory state information moved into system object
system parameter is not fs only for cpus
Implement drain() support in devices
Update for drain() call that returns number of times drain_event->process() will be called

Break O3 CPU! No sense in putting in a hack change that kevin is going to remove in a few minutes i imagine

src/cpu/simple/atomic.cc:
src/cpu/simple/atomic.hh:
    Since se mode has a system, allow access to it
    Verify that the atomic cpu is connected to an atomic system on resume
src/cpu/simple/base.cc:
    Since se mode has a system, allow access to it
src/cpu/simple/timing.cc:
src/cpu/simple/timing.hh:
    Update for new drain() call that returns number of times drain_event->process() will be called and memory state being moved into the system
    Since se mode has a system, allow access to it
    Verify that the timing cpu is connected to an timing system on resume

    Implement drain() support in devices
src/python/m5/config.py:
    Allow drain to return number of times drain_event->process() will be called. Normally 0 or 1 but things like O3 cpu or devices with multiple ports may want to call it many times
src/python/m5/objects/BaseCPU.py:
    move system parameter out of fs to everyone
src/sim/sim_object.cc:
src/sim/sim_object.hh:
    States are now running, draining, or drained. memory state information moved into system object
src/sim/system.cc:
src/sim/system.hh:
    memory mode information now contained in system object
