Merge branch 'jc/zlib-wrap'
* 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 Conflicts: sha1_file.c
