Integrate Python configuration script parsing into m5 itself.
SConscript: Add pyconfig/{pyconfig,code}.cc Add list of object description (.od) files. Include pyconfig/SConscript. base/inifile.cc: Get rid of CPP_PIPE... it never really worked anyway. base/inifile.hh: Make load(ifstream&) method public so pyconfig code can call it. sim/main.cc: Handle Python config scripts (end in '.py' instead of '.ini'). sim/pyconfig/m5configbase.py: Add license. Fix minor __setattr__ problem (2.3 related?) --HG-- rename : util/config/m5configbase.py => sim/pyconfig/m5configbase.py extra : convert_revision : 5e004922f950bfdefced333285584b80ad7ffb83
