Migrate most of main() and and all option parsing to python
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. --HG-- extra : convert_revision : c86b87a9f508bde1994088e23fd470c7753ee4c1
