Python classfile parser

[Gary Benson]

This morning I needed a classfile parser for a script I've been
writing, and I remembered that there was one in the ill-fated
katana.  I dug it out, tidied it up a bit, and stuck it here:

  http://inauspicious.org/files/scripts/classfile.py

Enjoy!

I've used that same parser code in gcjlib, and I've received a couple of
bug fixes for it, mostly related to parsing Sun javac generated
bytecode.

See http://gcc.gnu.org/ml/java/2005-08/msg00006.html for instance.

That's the earlier implementation, in Java.  I must've hit the same
out-of-order constant pool things as that guy, though, since I jumped
through hoops in the Python implementation to cope with it.

This assert looks fishy:

            assert not result.has_key(name)

I think there are some attributes which may validly appear multiple
times.
