style: [patch 1/22] use /r/3648/ to reorganize includes

trace: reimplement the DTRACE function so it doesn't use a vector
At the same time, rename the trace flags to debug flags since they
have broader usage than simply tracing. This means that
--trace-flags is now --debug-flags and --trace-help is now --debug-help

includes: sort all includes

eventq: convert all usage of events to use the new API.
For now, there is still a single global event queue, but this is
necessary for making the steps towards a parallelized m5.

Make the Event::description() a const function

Event descriptions should not end in "event"
(they function as adjectives not nouns)

Add Quiesce trace flag to track CPU quiesce/wakeup events.

Update copyright.

Change ExecContext to ThreadContext. This is being renamed to differentiate between the interface used objects outside of the CPU, and the interface used by the ISA. ThreadContext is used by objects outside of the CPU and is specifically defined in thread_context.hh. ExecContext is more implicit, and is defined by files such as base_dyn_inst.hh or cpu/simple/base.hh.

Further renames/reorganization will be coming shortly; what is currently CPUExecContext (the old ExecContext from m5) will be renamed to SimpleThread or something similar.

Change ExecContext to ThreadContext.

Fixes to get compiling to work. This is mainly fixing up some includes; changing functions within the XCs; changing MemReqPtrs to Requests or Packets where appropriate.

Currently the O3 and Ozone CPUs do not work in the new memory system; I still need to fix up the ports to work and handle responses properly. This check-in is so that the merge between m5 and newmem is no longer outstanding.

src/SConscript:
Need to include FU Pool for new CPU model. I'll try to figure out a cleaner way to handle this in the future.
src/base/traceflags.py:
Include new traces flags, fix up merge mess up.
src/cpu/SConscript:
Include the base_dyn_inst.cc as one of othe sources.
Don't compile the Ozone CPU for now.
src/cpu/base.cc:
Remove an extra } from the merge.
src/cpu/base_dyn_inst.cc:
Fixes to make compiling work. Don't instantiate the OzoneCPU for now.
