Update zlib 3rd party code to v1.2.11

zlib source code, version 1.2.11. https://www.zlib.net/.

Include all the gynmastics involved in:
- making sure we compile zlibstat and set the output files locations and filename to those expected by the starshatter setup.
- turning off the ASM includes as they are invalid for the new versions of zlib (and crash when running).
- matching the calling conventions of the Starshatter code by ommiting ZLIB_WINAPI from the zlib preprocessor defines.
- fix debug build compile error in zlibstatic:

This fixes some string warnings.

+Summary
+-------
+This directory contains ASM implementations of the functions
+longest_match() and inflate_fast(), for 64 bits x86 (both AMD64 and Intel EM64t),
+for use with Microsoft Macro Assembler (x64) for AMD64 and Microsoft C++ 64 bits.
+
+gvmat64.asm is written by Gilles Vollant (2005), by using Brian Raiter 686/32 bits
+   assembly optimized version from Jean-loup Gailly original longest_match function
+
+inffasx64.asm and inffas8664.c were written by Chris Anderson, by optimizing
+   original function from Mark Adler
+
+Use instructions
+----------------
+Assemble the .asm files using MASM and put the object files into the zlib source
+directory.  You can also get object files here:
+
+     http://www.winimage.com/zLibDll/zlib124_masm_obj.zip
+
+define ASMV and ASMINF in your project. Include inffas8664.c in your source tree,
+and inffasx64.obj and gvmat64.obj as object to link.
+
+
+Build instructions
+------------------
+run bld_64.bat with Microsoft Macro Assembler (x64) for AMD64 (ml64.exe)
+
+ml64.exe is given with Visual Studio 2005, Windows 2003 server DDK
+
+You can get Windows 2003 server DDK with ml64 and cl for AMD64 from
+  http://www.microsoft.com/whdc/devtools/ddk/default.mspx for low price)
