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?)
