[Python-Dev] Expanding max chunk size to 4GB.

[Mark Rages]

The RIFF chunk size (used by the Python wave library) is 2GB, because
the length is read as a signed 32-bit integer.

The attached patch to chunk.py raises the limit to 4GB by using a
signed integer.

Is this correct?

Is there a more general solution to 32-bit addressing limitation in
wave files?  Multiple chunks?  Set the length field to zero and let
software assume we only have one chunk?
