Smooth dataflow curve & Half CPU usage for client

_(Strongly Recommended for upgrading)_

Smooth dataflow curve by setting MaxStreamWindowSize to sockbuf(hidden).
Half CPU usage by using recv() syscall instead of recvfrom() syscall. (client only)

_（强烈建议升级）_

设置MaxStreamWindowSize 值为 sockbuf(隐)，以期望平滑数据传输曲线。
调整UDP接收的系统调用，recvfrom() 改为 recv()，降低客户端CPU消耗(一半以上)。

v20160808

Cumulative Non-Critical Updates

Updates(20160808):

Add hidden parameters
- sockbuf: send/recv buffer size of udp sockets, default to 4MB.(macOS limit, pre: 16MB.)
- keepalive: NAT keepalive interval(in seconds) to prevent your router from removing port mapping, default to 10s.(pre:5s.)
Optimized Algorithms:
- If TX queue is not empty, ping packet is unnecessary to fire.
- FEC search range is more precise.
- PAWS detection is not required in markData() of FEC.
- CLI parameters are parsed only once after startup. (provided by @buaazp)
- _Explicitly dereference data immediately, hopefully this would lower memory usage. (Update: 20160809)_
- _Do not update RTT for recovered packets from FEC. (Update: 20160810)_
API optimize
- Listener has it's own SetDSCP() function.

累计非关键更新(20160808):

增加隐藏参数
- sockbuf：用于调整udp socket的收发缓冲区大小, 默认值为4MB。(macOS限制, 前值为16MB。)
- keepalive：用于调整NAT keepalive的间隔时间，避免路由器清除端口映射。(默认值10s, 前值5s。)
优化的算法:
- 如果传输队列非空，则不需要发送ping包。
- FEC更精确的搜索范围。
- FEC的markData()不需要检测PAWS。
- 启动后只解析一次命令行参数。（@buaazp提供）
- _数据队列显式的去引用，希望能降低内存使用。(Update: 20160809)_
- _RTT计算优化，不计入通过FEC纠错而来的RTT。(Update: 20160810)_
API优化
- Listener实现独立的SetDSCP()函数。

_Compiler: go version go1.7rc6 darwin/amd64_

improve network latency by introducing stream mode

_Update 20160726: recompiled with go1.7rc3 && optimize ikcp_send for stream mode_
_Update 20160803: recompiled with go1.7rc5_

_Strongly Recommended for Upgrading_

the default packet mode operations of kcp would introduce HOL-blocking for a single message; by eliminating message boundary with _stream mode_, this problem has relived.

kcp默认包模式的传输会引入单包的Head Of Line 阻塞问题，因此通过修改kcp，并在kcp-go中增加了stream模式缓解此问题，以降低网络延迟。（官方已同步）

Compression with Snappy (The first compression enabled release)

_CAUTION: NOT COMPATIBLE WITH PREVIOUS RELEASES WITH DEFAULT SETTINGS._

_MAKE SURE TO VERIFY YOUR MD5 HASH BEFORE DEPLOY._
_STRONGLY RECOMMENDED FOR UPGRADING._

Add google snappy compression for transport layer to _accelerate_ data transfer(_enabled by default_) , use -nocomp on both side to disable.
Compression has no effect on _already encrypted_ data stream.

_注意：默认与以前版本不兼容（两端需同时升级）_

_部署之前请务必确认您的MD5哈希值_
_强烈建议升级_

使用google snappy算法对传输层做数据流压缩（_默认开启），_用于加速数据传输。
注意: 对于承载的数据**已经加密的**，没有明显效果。
