A severe bug introduced by https://github.com/xtaci/kcp-go/pull/65 prevents the server-side of kcptun from processing the incoming FEC packet now discovered(which leads to unnecessary retransmissions). This release has fixed that bug(by disposing the that feature), and the benchmark showed MUCH FASTER than previous versions.

EVERYONE is suggested to upgrade to this version, meanwhile, all functional PR will be rejected releated to kcp-go to prevent such mistakes.

1.Repack version v20171129, due to the profiling option in testing(port 6060), the binary size of client side(ONLY) is larger than the previous versions, this repacking fixed this issue, with no functional changes.

1. 只使用session定时器，避免kcp_update的thresh抖动。
2. rto计算中的clock granularity设置为 interval值。
3. 去掉rtomin的硬性限制。
4. 对于单个数据包中的所有ack，只使用最后一个ack计算rto。
5. -datashard/-parityshard 增加 -ds -ps 简写
