Summary: zipfile: support for ZIP64

Initial Comment:
The attached patch implements support for ZIP64, that is zipfiles 
containing very large (>4GByte) files and zipfiles that are larger than
4GByte themselves. 

The output of this patch can be read by pkzip (see below for the actual 
version I used for testing).

I'd like to see a testcase and possibly a note for the
documentation about the new semantics. Also, should it be
possible to say "don't use the ZIP64 extension, instead
raise an Error" for people who don't want to generate these?

Oops, I've uploaded the wrong file. zipfile-zip64.patch is the correct one.

I've tested the correctness of created archives using this version of pkzip:

pkzipc -version
