object and get rid of the ParamContext that each used to have.
python/m5/objects/Root.py:
Add max_time and progress_interval to the Root object
sim/root.cc:
Add max_time and progress_interval to the Root object. These
parameters used to be in their own contexts in sim_events.cc
sim/sim_events.cc:
Get rid of the ParamContext for max cycles and the progress
event. Move the functionality to the Root object
sim/sim_events.hh:
Move ProgressEvent declaration to the header so that it can
be used in other files.
