Transport&Security Enhancement!

🌻🌻IMPORTANT NOTICE: THIS VERSION IS THE LATEST STABLE RELEASE DURING SUMMER VACATION 2024 .🌻🌻
🌻🌻AFTER THIS, I'LL BE BUSIER🌻🌻

What's New?

1. Enhanced autotune stability.
2. Fixed an FEC boundary issue in timely-non-continuous packet.(Link is more stable)
3. Support for Quantum Permutation Pad for quantum-resistent communication, based on the implementation in https://github.com/xtaci/qpp .

   --QPP                            enable Quantum Permutation Pads(QPP)
   --QPPCount value                 the prime number of pads to use for QPP: The more pads you use, the more secure the encryption. Each pad requires 256 bytes. (default: 61)

Your could also specify

     "qpp":true,
     "qpp-count":61,

in your client and server side json file. These 2 parameters must be identical on both sides.
4. Added a closeWait(30 seconds) before terminating a connection pair, mitigating Firefox PR_END_OF_FILE_ERROR issue.
5. Fix socket-fd closing in '-tcp' mode, only available under linux, previous release may leak socket fds.
6. Build with well-organized codes.

go1.21 rebuild

1. use clear to zero slice in kcp-go.
2. use default.pgo to optimize code generation in kcptun/client side
3. compiler upgraded to go 1.21
4. added an option -pprof on client side to support PGO
