X86: Make the local APICs register themselves with the IO APIC.
...
This is a hack so that the IO APIC can figure out information about the local
APICs. The local APICs still have no way to find out about each other.
Ideally, when the local APICs update state that's relevant to somebody else,
they'd send an update to everyone. Without being able to do a broadcast, that
would still require knowing who else there is to notify. Other broadcasts are
implemented using assumptions that may not always be true.

mem: use single BadAddr responder per system.
...
Previously there was one per bus, which caused some coherence problems
when more than one decided to respond. Now there is just one on
the main memory bus. The default bus responder on all other buses
is now the downstream cache's cpu_side port. Caches no longer need
to do address range filtering; instead, we just have a simple flag
to prevent snoops from propagating to the I/O bus.

For some reason o3 FS init() only called initCPU if the thread state

stats: Add a wrapper class for the information side of things.
...
This provides an easy way to provide the callbacks into the data side
of things from the info side of things. Rename Wrap to DataWrap so it
is more easily distinguishable from InfoWrap

stats: better naming of template parameters for the wrapper stuff

Parent and Child are bad names. Derived and Base are better.

make handling of interstage buffers (i.e. StageQueues) more consistent: (1)number from 0-n, not 1-n+1, (2) always check nextStageValid before a stageNum+1 and prevStageValid for a stageNum-1 reference (3) add skidSize() to get StageQueue size for all threads

InOrder didnt have all it's params set to a default value, which is now required for M5 objects; Also, a # of values need to be reset to 0 (or the appropriate value) before we assume they are OK for use.
