[issue27164] zlib can't decompress DEFLATE using shared dictionary

[Xiang Zhang]

Xiang Zhang added the comment:

I think my conclusion in last message is right. A similar bug in CPAN can be found in https://rt.cpan.org/Public/Bug/Display.html?id=36046. And I can find in zlib's changelog inflateSetDictionary starts to support raw inflate from 1.2.2.1.

Patch attached now allows Python to decompress raw deflate format with a dictionary. Hope some core devs are willing to review.
