Major cleanup of python config code.
Special mpy importer is gone; everything is just plain Python now (funky, but straight-up). May not completely work yet... generates identical ini files for many configs/kernel settings, but I have yet to run it against regressions. This commit is for my own convenience and won't be pushed until more testing is done. python/m5/__init__.py: Get rid of mpy_importer and param_types. python/m5/config.py: Major cleanup. We now have separate classes and instances for SimObjects. Proxy handling and param conversion significantly reorganized. No explicit instantiation step anymore; we can dump an ini file straight from the original tree. Still needs more/better/truer comments. test/genini.py: Replace LoadMpyFile() with built-in execfile(). Export __main__.m5_build_env. python/m5/objects/AlphaConsole.py: python/m5/objects/AlphaFullCPU.py: python/m5/objects/AlphaTLB.py: python/m5/objects/BadDevice.py: python/m5/objects/BaseCPU.py: python/m5/objects/BaseCache.py: python/m5/objects/BaseSystem.py: python/m5/objects/Bus.py: python/m5/objects/CoherenceProtocol.py: python/m5/objects/Device.py: python/m5/objects/DiskImage.py: python/m5/objects/Ethernet.py: python/m5/objects/Ide.py: python/m5/objects/IntrControl.py: python/m5/objects/MemTest.py: python/m5/objects/Pci.py: python/m5/objects/PhysicalMemory.py: python/m5/objects/Platform.py: python/m5/objects/Process.py: python/m5/objects/Repl.py: python/m5/objects/Root.py: python/m5/objects/SimConsole.py: python/m5/objects/SimpleDisk.py: python/m5/objects/Tsunami.py: python/m5/objects/Uart.py: Fixes for eliminating mpy_importer, and modified handling of frequency/latency params.
