1) return the periodicity of checkpoints back into the code (i.e. make m5 checkpoint n m meaningful again).
2) to do this, i had to much around with being able to repeatedly schedule and SimLoopExitEvent, which led to changes in how exit simloop events are handled to make this easier.

src/sim/sim_exit.hh:
add the periodicity of checkpointing back into the code.
to facilitate this, there are now two wrappers (instead of just overloading exitSimLoop). exitSimLoop is only for exiting NOW (i.e. at curTick), while schedExitSimLoop schedules and exit event for the future.

Eventually support for different OSs can be added so you can specify which versions of the binary you want to run from one config file.

Key new functions that can be called on the m5 object at the python interpreter:
doQuiesce(root) - A helper function that quiesces the object passed in and all of its children.
resume(root) - Another helper function that tells the object and all of its children that the quiesce is over.
checkpoint(root) - Takes a checkpoint of the system. Checkpoint directory must be set before hand.
setCheckpointDir(name) - Sets the checkpoint directory.
restoreCheckpoint(root) - Restores the values from the checkpoint located in the checkpoint directory.
changeToAtomic(system) - Changes the system and all of its children to atomic memory mode.
changeToTiming(system) - Changes the system and all of its children to timing memory mode.
switchCpus(list) - Takes in a list of tuples, where each tuple is a pair of (old CPU, new CPU). Quiesces the old CPUs, and then switches over to the new CPUs.
src/SConscript:
Remove serializer, replaced by python code.
src/python/m5/__init__.py:
Updates to support quiescing, checkpointing, changing memory modes, and switching CPUs.
src/python/m5/config.py:
Several functions defined on the SimObject for quiescing, changing timing modes, and switching CPUs
src/sim/main.cc:
Add some extra functions that are exported to python through SWIG.
src/sim/serialize.cc:
Change serialization around a bit. Now it is controlled through Python, so there's no need for SerializeEvents or SerializeParams.
Also add in a new unserializeAll() function that loads a checkpoint and handles unserializing all objects.
src/sim/serialize.hh:
Add unserializeAll function and a setCheckpointName function.
src/sim/sim_events.cc:
Add process() function for CountedQuiesceEvent, which calls exitSimLoop() once its counter reaches 0.
src/sim/sim_events.hh:
Add in a CountedQuiesceEvent, which is used when the system is preparing to quiesce. Any objects that can't be quiesced immediately are given a pointer to a CountedQuiesceEvent. The event has its counter set via Python, and as objects finish quiescing they call process() on the event. Eventually the event causes the simulation to stop once all objects have quiesced.
src/sim/sim_object.cc:
Add a few functions for quiescing, checkpointing, and changing memory modes.
src/sim/sim_object.hh:
Add a state variable to all SimObjects that tracks both the timing mode of the object and the quiesce state of the object. Currently this isn't serialized, and I'm not sure it needs to be so long as the timing mode starts up the same after a checkpoint.

Key was adding support for cloning port references (trickier than it sounds).
Got rid of class/instance thing and go back to instance cloning...
still don't allow changing SimObject parameters/children after a
class (instance) has been subclassed or instantiated (or cloned), which
should avoid bizarre unintended behavior.
configs/test/fs.py:
Add ".port" to busses to get a port reference.
Get rid of commented-out code.
src/python/m5/__init__.py:
resolveSimObject should call getCCObject() instead of createCCObject()
to avoid cycles in recursively creating objects.
src/python/m5/config.py:
Get rid of class/instance thing and go back to instance cloning.
Deep copy has to happen only on instance cloning then (and not on subclassing).
Add getCCObject() method to force creation of C++ SimObject without
recursively creating its children.
Add support for cloning port references (trickier than it sounds).
Also clean up some very obsolete comments.

To support this, also renamed (read|write)[1248] on memory_object and

a few template functions (though with a level of indirection so that
the interface can remain virtual). I did not do that though.
