* add simple port check functions
* release sock lock when manager exit
* simplfy the sock lock
* release sock lock when receive the stat report
* simplfy dns query
* add udp port check
* enable port check function
* clean code and logs
Add experimental HTTP/TLS obfuscating as an **optional extension** of shadowsocks protocol.
More discussions can be found here: https://github.com/shadowsocks/shadowsocks-org/issues/26
As this feature is still a SIP (Shadowsocks Improvement Proposal), it's very unstable and experimental. So,
1. Don't enable it unless you know what it is.
2. Be very careful when using it in production environment.
In Mac OS X 10.10, `launch_activate_socket` was introduced.
So whenever the port is requested, the `launchd` can launch the program
dynamically. A possible plist may like this:
```
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.github.shadowsocks</string>
<key>ProgramArguments</key>
<array>
<string>/path/to/ss-local</string>
<string>-s</string>
<string>server host</string>
<string>-p</string>
<string>server port</string>
<!-- the -l and -b can be ommited, as launchd takes over it -->
<string>-k</string>
<string>password</string>
<string>-m</string>
<string>method</string>
<string>-t</string>
<string>timeout</string>
<string>-A</string>
</array>
<key>Sockets</key>
<dict>
<!-- the name is hard coded in ss-local -->
<key>Listeners</key>
<dict>
<key>SockNodeName</key>
<string>127.0.0.1</string>
<key>SockServiceName</key>
<string>socks</string>
</dict>
</dict>
</dict>
</plist>
```
The magic is `launchd` will listen to the `SockServiceName`, when the port
is requested, the `ss-local` will be launched.
- GNU treats void* as char* when doing pointer arithmetic, so let's make it clear
- Fix memory leak, save copy from malloc() and pass the original pointer to free()
- minor type mismatches
