[issue3492] Zlib compress/decompress functions returning bytearray

[Gregory P. Smith]

Gregory P. Smith <greg at krypto.org> added the comment:

this is a very simple patch and makes sense to me.  marking it a release 
blocker and asking about it on the mailing list.  if anyone disagrees 
with this one please speak up.

in general IO input functions elsewhere return bytes().  zlib should as 
well.  this fixes that.
