Link in Python interpreter.

Use embedded zip archive to carry Python code instead
of homegrown embedded string/file mechanism.
Do argument parsing in Python instead of C++.

SConstruct:
    Add Python interpreter include path & library.
    Define two new simple builders which copy &
    concatenate files, respectively, for use by
    the Python embedded zipfile code.
src/SConscript:
    Encapsulate environment creation in a function.
    Add code to append Python zip archive to final executable.
    Eliminate references to obsolete files.
src/python/SConscript:
    Rewrite to generate embedded zip archive of Python code
    (replacing old "embedded string" mechanism).
src/python/m5/__init__.py:
    Move main arg-parsing loop here (out of C++ main()).
src/python/m5/config.py:
    Minor fix (version incompatibility?).
src/sim/main.cc:
    Invoke embedded Python interpreter to parse args
    and generate config.ini, replacing C++ arg parsing code.
