feat(vfs): Implement append lock manager for file operations ( #1483 )
...
* feat(vfs): Implement append lock manager for file operations
- Introduced an `AppendLockManager` to ensure atomicity for append operations across filesystems, preventing data corruption in concurrent write scenarios.
- Updated file write methods to utilize the new append lock mechanism, ensuring that appending to files respects the latest end-of-file position.
- Enhanced `write_append` and `pwrite_append` methods to support forced append semantics, aligning with Linux behavior.
- Initialized the append lock manager during VFS initialization to ensure it is ready before any file write operations.
This addition improves the reliability of file operations in a multi-threaded environment, particularly for append scenarios.

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

支持解析启动命令行参数，行为与Linux一致。具体见文档。
bbs链接：https://bbs.dragonos.org.cn/t/topic/362
issue: https://github.com/DragonOS-Community/DragonOS/issues/865
支持了三种参数：
- Arg （不带Value的参数）
- KV （正常的KV参数）
- EarlyKV (在内存管理初始化之前解析）
# TODO
- 支持在`/proc/cmdline`下面查看内核启动时的命令行参数。
- 支持回调函数，允许更加灵活的设置参数的值（目前用不到，就没写了）
