chore: Release v3.1.0

* Explicitly call gai_strerrorA (for Windows builds), so that the code work correctly in 32bit or 64bit builds.

* Implement GAI_STRERROR macro to deal with Windows vs. Non-Windows compiles for 64-bit.

* make usocket.c consistent with other modules that call macro GAI_STRERROR

* Use different name not just different case for macro wrapping function

+# Changelog
+
+## [v3.1.0](https://github.com/lunarmodules/luasocket/releases/v3.1.0) — 2022-07-27
+
+* Add support for TCP Defer Accept – @Zash
+* Add support for TCP Fast Open – @Zash
+* Fix Windows (mingw32) builds – @goldenstein64
+* Avoid build warnings on 64-bit Windows – @rpatters1
+
+## [v3.0.0](https://github.com/lunarmodules/luasocket/releases/v3.0.0) — 2022-03-25
+
+The last time LuaSocket had a stable release tag was 14 years ago when 2.0.2 was tagged.
+A v3 release candidate was tagged 9 years ago.
+Since then it has been downloaded over 3 million times.
+Additionally the Git repository regularly gets several hundred clones a day.
+But 9 years is a long time and even the release candidate has grown a bit long in the tooth.
+Many Linux distros have packaged the current Git HEAD or some specific tested point as dated or otherwise labeled releases.
+256 commits later and having been migrated to the @lunarmodules org namespace on GitHub, please welcome v3.
+
+This release is a "safe-harbor" tag that represents a minimal amount of changes to get a release tagged.
+Beyond some CI tooling, very little code has changed since migration to @lunarmodules ([5b18e47..e47d98f](https://github.com/lunarmodules/luasocket/compare/5b18e47..e47d98f?w=1)):
+
+* Lua 5.4.3+ support – @pkulchenko, @Zash
+* Cleanup minor issues to get a code linter to pass – @Tieske, @jyoui, @alerque
+* Update Visual Studio build rules for Lua 5.1 – @ewestbrook
+* Set http transfer-encoding even without content-length – @tokenrove
+
+Prior to migration to @lunarmodules ([v3.0-rc1..5b18e47](https://github.com/lunarmodules/luasocket/compare/v3.0-rc1..5b18e47?w=1)) many things happened of which the author of this changelog is not fully apprised.
+Your best bet if it affects your project somehow is to read the commit log & diffs yourself.
+
+## [v3.0-rc1](https://github.com/lunarmodules/luasocket/releases/v3.0-rc1) — 2013-06-14
+
+Main changes for LuaSocket 3.0-rc1 are IPv6 support and Lua 5.2 compatibility.
+
+* Added: Compatible with Lua 5.2
+  - Note that unless you define LUA_COMPAT_MODULE, package tables will not be exported as globals!
+* Added: IPv6 support;
+  - Socket.connect and socket.bind support IPv6 addresses;
+  - Getpeername and getsockname support IPv6 addresses, and return the socket family as a third value;
+  - URL module updated to support IPv6 host names;
+  - New socket.tcp6 and socket.udp6 functions;
+  - New socket.dns.getaddrinfo and socket.dns.getnameinfo functions;
+* Added: getoption method;
+* Fixed: url.unescape was returning additional values;
+* Fixed: mime.qp, mime.unqp, mime.b64, and mime.unb64 could mistaking their own stack slots for functions arguments;
+* Fixed: Receiving zero-length datagram is now possible;
+* Improved: Hidden all internal library symbols;
+* Improved: Better error messages;
+* Improved: Better documentation of socket options.
+* Fixed: manual sample of HTTP authentication now uses correct "authorization" header (Alexandre Ittner);
+* Fixed: failure on bind() was destroying the socket (Sam Roberts);
+* Fixed: receive() returns immediatelly if prefix can satisfy bytes requested (M Joonas Pihlaja);
+* Fixed: multicast didn't work on Windows, or anywhere else for that matter (Herbert Leuwer, Adrian Sietsma);
+* Fixed: select() now reports an error when called with more sockets than FD_SETSIZE (Lorenzo Leonini);
+* Fixed: manual links to home.html changed to index.html (Robert Hahn);
+* Fixed: mime.unb64() would return an empty string on results that started with a null character (Robert Raschke);
+* Fixed: HTTP now automatically redirects on 303 and 307 (Jonathan Gray);
+* Fixed: calling sleep() with negative numbers could block forever, wasting CPU. Now it returns immediately (MPB);
+* Improved: FTP commands are now sent in upper case to help buggy servers (Anders Eurenius);
+* Improved: known headers now sent in canonic capitalization to help buggy servers (Joseph Stewart);
+* Improved: Clarified tcp:receive() in the manual (MPB);
+* Improved: Decent makefiles (LHF).
+* Fixed: RFC links in documentation now point to IETF (Cosmin Apreutesei).

-<h2 id=whatis>What is LuaSocket?</h2>
-
-<p>
-LuaSocket  is a  <a href="http://www.lua.org">Lua</a>  extension library
-that is composed by two parts: a C core that provides  support for the TCP
-and UDP transport layers, and a set of Lua modules that add support for
-functionality commonly needed by applications that deal with the Internet. 
-</p>
-
-<p>
-The core support has been  implemented so that it  is both efficient and
-simple to use.  It is available to any Lua application once it has been
-properly initialized by the interpreter in use. The code has been tested

-Among the support modules, the most commonly used implement the 
-<a href=smtp.html>SMTP</a>
-(sending  e-mails),  
-<a href=http.html>HTTP</a>
-(WWW access)  and  
-<a href=ftp.html>FTP</a>  
-(uploading  and downloading files) client
-protocols. These provide a very natural and generic interface to the
-functionality defined by each protocol. 
-In addition, you will find that the 
-<a href=mime.html>MIME</a> (common encodings), 
-<a href=url.html>URL</a> 
-(anything you could possible want to do with one) and 
-<a href=ltn12.html>LTN12</a> 
-(filters, sinks, sources and pumps) modules can be very handy.

-The library is available under the same  
-<a href="http://www.lua.org/copyright.html">
-terms and conditions</a> as the Lua language, the MIT license. The idea is
-that if you can use Lua in a project, you should also be able to use 
-LuaSocket.

-<h2 id=download>Download</h2>
-
-<p>
-LuaSocket version 3.0-rc1 is now available for download! 
-It is compatible with  Lua&nbsp;5.1 and 5.2, and has    
-been tested on Windows&nbsp;XP, Linux, and Mac OS X. Chances
-are it works well on most UNIX distributions and Windows flavors.
-</p>
-
-<p>
-The current version of the library can be found at
-the <a href="https://github.com/diegonehab/luasocket">LuaSocket
-project page</a> on GitHub. Besides the full C and Lua source code 
-for the library, the distribution contains several examples, 
-this user's manual and basic test procedures.
-</p>
-
-<p> Take a look at the <a
-href=installation.html>installation</a> section of the

-
-<h2 id=thanks>Special thanks</h2>
-
-<p>
-This marks the first release of LuaSocket that
-wholeheartedly embraces the open-source development
-philosophy. After a long hiatus, Matthew Wild finally
-convinced me it was time for a release including IPv6 and
-Lua 5.2 support. It was more work than we anticipated.
-Special thanks to Sam Roberts, Florian Zeitz, and Paul
-Aurich, Liam Devine, Alexey Melnichuk, and everybody else
-that has helped bring this library back to life.

+<h2 id="whatis">What is LuaSocket?</h2>
+
+<p>
+LuaSocket  is a  <a href="http://www.lua.org">Lua</a>  extension library
+that is composed by two parts: a C core that provides  support for the TCP
+and UDP transport layers, and a set of Lua modules that add support for
+functionality commonly needed by applications that deal with the Internet.
+</p>
+
+<p>
+The core support has been  implemented so that it  is both efficient and
+simple to use.  It is available to any Lua application once it has been
+properly initialized by the interpreter in use. The code has been tested
+and runs well on several Windows and UNIX platforms. </p>
+
+<p>
+Among the support modules, the most commonly used implement the
+<a href="smtp.html">SMTP</a>
+(sending  e-mails),
+<a href="http.html">HTTP</a>
+(WWW access)  and
+<a href="ftp.html">FTP</a>
+(uploading  and downloading files) client
+protocols. These provide a very natural and generic interface to the
+functionality defined by each protocol.
+In addition, you will find that the
+<a href="mime.html">MIME</a> (common encodings),
+<a href="url.html">URL</a>
+(anything you could possible want to do with one) and
+<a href="ltn12.html">LTN12</a>
+(filters, sinks, sources and pumps) modules can be very handy.
+</p>
+
+<p>
+The library is available under the same
+<a href="http://www.lua.org/copyright.html">
+terms and conditions</a> as the Lua language, the MIT license. The idea is
+that if you can use Lua in a project, you should also be able to use
+LuaSocket.

+<p>
+LuaSocket version 3.1.0 is now available for download!
+It is compatible with Lua&nbsp;5.1 through 5.4.
+Chances are it works well on most UNIX distributions and Windows flavors.

+
+<p>
+The current version of the library can be found at
+the <a href="https://github.com/lunarmodules/luasocket">LuaSocket

+Lua 5.2 support. It was more work than we anticipated.
+Special thanks to Sam Roberts, Florian Zeitz, and Paul
+Aurich, Liam Devine, Alexey Melnichuk, and everybody else
