[issue14366] Suporting bzip2 and lzma compression in zip files

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

ZIP files specification supports new compression algorithms since 2006. Since 
bzip2 and lzma now contained in Python standart library, it would be nice to 
add support for these methods in zipfile. This will allow to process more 
foreign zip files and create more compact distributives.

The proposed patch adds two new methods ZIP_BZIP2 and ZIP_LZMA, which are 
automatically detecting when unpacking and that can be used for packing.

Serhiy Storchaka  added the comment:

This is not completed patch yet, without tests and documentation. I would like 
to receive feedback before the end of polishing. It might be worth transfer a 
portion of code in _lzmamodule.c for better use of capacity of LZMA API (used 
in zip format somewhat differs from LZMA_ALONE).
