configs/test/fs.py:
configs/test/test.py:
update for the new way that m5 deals with options
src/python/SConscript:
Compile AUTHORS, LICENSE, README, and RELEASE_NOTES into the
python stuff.
src/python/m5/__init__.py:
redo the way options work.
Move them all to main.py
src/sim/main.cc:
Migrate more functionality for main() into python.
Namely option parsing
src/python/m5/attrdict.py:
A dictionary object that overrides attribute access to
do item access.
src/python/m5/main.py:
The new location for M5's option parsing, and the main()
routine to set up the simulation.
