Bluewing Server update to build 39

The edits that affect bluewing-cpp-server include:
* IPv6 fixes for changing outgoing IPv6 address
* Chance of Windows UDP corruption fixed (odds were more likely in server)
* UDP size limit errors added
* Windows socket startup checked
* UDP no longer closes prematurely (this fixes a crash on disconnect/reconnect for Wine)
* CG-NAT client support added
* Unicode allowlist error report fixed
* Fixed single-threaded channel close

More details available in original commit SortaCore/MMF2Exts@a018f8e .
