feat(ebpf):[WIP] add eBPF support (#948) 
* feat(kprobe): Add basic kprobe support for x86_64

* feat: add ebpf support (#912)

- 实现bpf()一部分命令，包括几种基本map，相关的helper函数
- 实现部分perf相关的数据结构
- 暂时为文件实现简单mmap
- 实现一个使用kprobe统计syscall 调用次数的ebpf程序

对eBPF支持程度(基本)：

- 简单的eBPF程序(没有指定特殊的Map)
- 使用内核已经实现的Map的eBPF程序
- 可以和kprobe配合使用
- 内核Map相关的接口定义已经实现，添加新的Map较为简单

不支持的功能:
- 区分不同的eBPF程序类型(Network/Cgroup)并限定可调用的helper函数集
- 与内核其它跟踪机制配合(tracepoint)
- 其它helper和Map


todo

- [ ]  修改mmap，需要讨论，因为这个和块缓存层相关
- [x]  添加文档
- [x]  修复可能的错误
- [x] 增加rbpf版本信息
