Merge branch 'jc/zlib-wrap' into maint

* jc/zlib-wrap:
  zlib: allow feeding more than 4GB in one go
  zlib: zlib can only process 4GB at a time
  zlib: wrap deflateBound() too
  zlib: wrap deflate side of the API
  zlib: wrap inflateInit2 used to accept only for gzip format
  zlib: wrap remaining calls to direct inflate/inflateEnd
  zlib wrapper: refactor error message formatter
