Kcptun: doesn't support SIP003?can't use udp relay when using kcptun?

[zkpig123]

问问题前先搜索ISSUE，并搞清楚下面的问题:

1. 检查 -key xxx 至少三遍, 保证两边一致。
2. 保证-nocomp, -datashard, -parityshard, -key, -crypt两边一致。
3. 是否在服务器端，正确设定了转发的目标服务器地址 --target。
4. 如果第3条不确定，尝试在服务器上telnet target port试试。
5. 防火墙是否关闭了UDP通信。
6. 两端的版本是否一致？
7. 是不是最新版本？
8. 两端分别是什么操作系统？
9. 两端的输出日志是什么？

Before firing issue, make sure you figured out the following common questions.

PLEASE DO SEARCH FIRST.

1. Check your -key xxx for at least 3 times, MAKE SURE both sides share the same secret.
2. -nocomp, -datashard, -parityshard, -key, -crypt must be the same on both side.
3. Did you correctly set the -target on the server side?
4. MAKE SURE telnet target port on your server successful(don't ask me why couldn't).
5. Does your firewall allows UDP communications? (including your ISP Cable-Modem)
6. Are you using the same version for both client & server
7. Are you using the latest release?
8. Which OS do you use?
9. Which end for this issue related to, client or server?

其实要让kcptun支持SIP003不难，自己写个bash脚本就可以了，接收从环境变量传过来的四个参数SS_REMOTE_HOST, SS_REMOTE_PORT, SS_LOCAL_HOST, SS_LOCAL_PORT，再传给kcptun就可以了
