If we define ZLIB_CONST before including zlib.h, zlib augments some interfaces with const decorations. By doing that we can keep our own interfaces cleaner and can remove some unconstify calls. ZLIB_CONST was introduced in zlib 1.2.5.2 (17 Dec 2011). When compiling with older zlib releases, you might now get compiler warnings about discarding qualifiers. CentOS 6 has zlib 1.2.3, but in 8e278b6576, we removed support for the OpenSSL release in CentOS 6, so it seems ok to de-support the zlib release in CentOS 6 as well.
