z_stream.next_in is non-const. Although currently Zlib doesn't modify buffer content on deflate(), it might be change in the future. gzwrite() already modify it. To avoid this let's change signature of git_filebuf.write and rework git_filebuf_write() accordingly. Signed-off-by: Kirill A. Shutemov <kirill@shutemov.name>
