All-in-one go testing library
在java或者c#这样的语言中，支持在单元测试的时候动态生成接口的mock类, 在rust中，也支持添加特性的形式来支持动态生成mock. c系列的语言，一般没这功能。目前项目所有的底层依赖包全都生成了mock静态文件，即使用不到, 这体验非常差. go的编译器也比较弱，对于动态加载go代码支持也比较差. xgo如果是从编译器层面提供支持，应该可以添加这个功能，也是亮点.
The problem is: is it possible to call arbitrary function through http without modifying any code? The answer is: it is possible, and could be a major feature of xgo....
Currently init functions are skipped, that makes it impossible to inject mock and collect trace during the init stage. However since init functions just run once and run serially, it...
Some function may modify it's input, and some may not. For these modifying the input, serializing the snapshot helps to improve the trace accuracy. And it's better to support this...
Do not require user to manually modify the code, the tool can automatically parse the code and rewrite gomonkey API calls to xgo

This has positive impact on performance since only a small portion of the program will be intercepted
When writing asserts, could we just naturally do the actual check without repeating any name? Current situation: ```go if result!="1234"{ t.Fatalf("expect result to be %s, actual: %s", "123", result) }...
