bumped version to 1.9.7.1.

* upgraded ngx_lua to 0.9.18rc1 to support Win32 LuaJIT DLL.
* upgraded lua-redis-parser to 0.11rc1 for better Win32 support.
* upgraded lua-rds-parser to 0.06rc2 for better Win32 support.
* upgraded ngx_rds_csv to 0.07rc1  for better Win32 support.
* upgraded lua-resty-cli to 0.04rc1 for better Win32 support.
* upgraded lua-resty-core to 0.1.2.
* applied a patch to LuaJIT to add "!/lualib/" to the default Lua
  package search paths.
* upgraded lua-cjson to 2.1.0.3rc2 for better Win32 support and
  a suppressed gcc warning.
* use OpenResty's nginx tarballs extracted directly from the official nginx
  code repos, because we need the win32 support which is excluded in the
  official nginx release tarballs. Our nginx release tarballs are
  generated by the util/package-nginx.sh script.
* added the util/package-win32.sh script to generate the Win32 OpenResty
  binary distribution file.
* applied a patch to always enable C compiler feature tests in nginx's
  own build system because the MinGW gcc compiler on Win32 is also
  powerful enough to support advanced features like variadic macros.
* added document README-win32.
* util/dist-check: do a partial uninstallation before installing
  anything new.
* added util/build-win32.sh to build OpenResty on Win32 using the
  MinGW/MSYS toolchain.
* ./configure: added support for building on Win32 using the MinGW/MSYS
  toolchain.

+README-win32 - README for the Windows 32-bit build of OpenResty
+
+Description
+===========
+
+The binary distributions of OpenResty can be downloaded from the following web page:
+
+https://openresty.org/#Download
+
+To start the NGINX server of the nginx server of the Win32 binary distribution of OpenResty:
+
+```bash
+start nginx
+```
+
+You can also specify the `-p PATH/` option to override the default server prefix, as in
+
+```bash
+cd /path/to/my/openresty/app/
+start nginx -p $PWD
+```
+
+Then you can use the `tasklist` command to check the nginx processes running in the background:
+
+```console
+C:\> tasklist /fi "imagename eq nginx.exe"
+
+Image Name                     PID Session Name        Session#    Mem Usage
+========================= ======== ================ =========== ============
+nginx.exe                     4616 Console                    1      7,412 K
+nginx.exe                     5836 Console                    1      7,800 K
+
+```
+
+One of the two processes is the master process while the other is the worker.
+
+If you are using the MSYS bash instead of the `cmd.exe` console, then you should replace the `/fi` option
+with `-fi` in the command above instead.
+
+You can quickly shut down the server like this:
+
+```bash
+nginx -s stop
+```
+
+or gracefully shut it down like this:
+
+```bash
+nginx -s quit
+```
+
+You can also forcibly kill the nginx processes via their PIDs with `taskkill`, as in
+
+```console
+C:\> taskkill /pid 5488 /F
+```
+
+where the PID (5488 in this example) can be found via the aforementioned `tasklist` command.
+
+Again, you should use the form `-pid` and `-F` for the options if you are in an MSYS bash
+session.
+
+Similarly, you can use the `nginx -s reload` command to reload nginx configurations without
+stopping the server. And you can use `nginx -s reopen` to instruct nginx to re-open
+all the log files.
+
+You can run the `resty` script like this:
+
+```console
+C:\> resty -e "ngx.say('Hello, OpenResty!')"
+Hello, OpenResty!
+```
+
+The `resty` command-line utility requires a Perl interpreter installed in your
+system and visible to your PATH environment. Any perl distributions should
+work, including StrawberryPerl, ActivePerl, and MSYS perl (the former two are
+recommended though).
+
+Debugging
+=========
+
+Debug symbosl are enabled even in release builds. So that when things go very wrong,
+one can still debug things with tools like MSYS GDB.
+
+Inclusion of debug symbols make the binary files (`.exe` and `.dll` files) much larger,
+but it generally will not load into memory during normal execution on a modern operating
+system.
+
+Caveats
+=======
+
+The Win32 port of the NGINX core supports the good old `select` IO multiplexing mechanism
+only.
+The I/O Completion Ports (IOCP) feature is *not* supported (yet). So do not use this build
+for production environments with very high concurrency levels.
+
+This Win32 build of OpenResty is mainly for developers who want to develop their applications
+in native Windows environment (though they eventually push the finished work onto a Linux or *BSD box, most of the time).
+
+TODO
+====
+
+* Add support for more than one NGINX worker processes.
+* Add support for concurrent connections more than 1024.
+* Switch to the Microsoft Visual Studio compiler toolchain for better performance and easier binary
+package redistribution.
+* Bundle StrawberryPerl to make command-line utilities like `resty` work out of the box (without
+manually installing a Perl).
+* Deliver an alternative Win32 binary package built with best debuggin capabilities (like enabling
+NGINX debugging logs, disabling C compiler optimizations, and enabling all the assertions and checks).
+* Deliver binary packages for 64-bit Windows (Win64).
+
+Details About The Building Process
+==================================
+
+Usually you do not need to worry about how the Win32 binaries were built on the maintainers''
+side. But if you do, please read on.
+
+The Win32 build of OpenResty is currently built via the MinGW/MSYS toolchain, including
+MinGW gcc 4.8.1, MSYS perl, MSYS bash, MSYS make, and etc. Basically, it is currently built via
+ the following cmmands:
+
+```bash
+mkdir -p objs/lib || exit 1
+cd objs/lib || exit 1
+ls ../../..
+tar -xf ../../../openssl-1.0.2d.tar.gz
+tar -xf ../../../zlib-1.2.8.tar.gz
+tar -xf ../../../pcre-8.37.tar.gz
+cd ../..
+./configure --with-cc=gcc \
+    --prefix= \
+    --with-cc-opt='-DFD_SETSIZE=1024' \
+    --with-select_module \
+    --with-ipv6 \
+    --sbin-path=nginx.exe \
+    --with-pcre-jit \
+    --with-luajit-xcflags="-DLUAJIT_NUMMODE=2 -DLUAJIT_ENABLE_LUA52COMPAT" \
+    --with-pcre=objs/lib/pcre-8.37 \
+    --with-zlib=objs/lib/zlib-1.2.8 \
+    --with-openssl=objs/lib/openssl-1.0.2d \
+    -j5
+make
+make install
+```
+
+where the dependency library source tarballs for OpenSSL, Zlib, and PCRE are downloaded
+from their official sites, respectively.
+
+We automate these commands in a dedicated shell script named [build-win32.sh](https://github.com/openresty/ngx_openresty/blob/master/util/build-win32.sh).
+
+Furthermore, we automate the packaging process of the resulting binaries and supporting files
+with this [package-win32.sh](https://github.com/openresty/ngx_openresty/blob/master/util/package-win32.sh)
+script.
+
+Usually you can just download and use the binary distribution of OpenResty without
+installing the build toolchain.

+Upstream: fixed $upstream_response_time for filter_finalize + error_page.
+
+ngx_http_upstream_finalize_request() is always called twice when an
+output filter module calls ngx_http_filter_finalize_request() *and*
+a custom error page is configured by the error_page directive. This
+is because
+
+1. ngx_http_filter_finalize_request() triggers
+        calling ngx_http_terminate_request
+        => calling ngx_http_upstream_cleanup
+        => calling ngx_http_upstream_finalize_request
+
+2. ngx_http_internal_redirect() returns NGX_DONE
+        ==> ngx_http_special_response_handler() returns NGX_DONE
+        ==> ngx_http_filter_finalize_request() returns NGX_ERROR
+        ==> ngx_http_send_header() returns NGX_ERROR
+        ==> ngx_http_upstream_send_response() calls
+            ngx_http_upstream_finalize_request() again in the same
+            ngx_http_upstream_send_response() call as 1).
+
+This might result in corrupted $upstream_response_time values (close
+to the absolute timestamp value) when u->state->response_sec happens
+to be non-zero.
+
+This patch ensures that the $upstream_response_time value is only
+calculated upon the first ngx_http_upstream_finalize_request()
+invocation.

+Upstream: SSL handshake timeouts.

+Timeout may not be set on an upstream connection when we call
+ngx_ssl_handshake() in ngx_http_upstream_ssl_init_connection(),
+so make sure to arm it if it's not set.
