1.完成fork的主体逻辑 2.将文件系统接到新的pcb上 3.经过思考,暂时弃用signal机制,待进程管理重构完成后,重写signal机制.原因是原本的signal机制太烂了

1.删除旧的fork 2.删除signal相关代码,等进程管理重构结束之后,再重新写. 3.调整了fork/vfork/execve系统调用
* 实现切换进程的代码
* 修改设置preempt的代码 * 删除rust的list和refcount
* 为每个核心初始化idle进程
#336) * 把调度器的pcb替换为新的Arc<ProcessControlBlock> * 把调度器队列锁从 RwSpinLock 替换为了 SpinLock ，修改了签名以通过编译 * 修正一些双重加锁、细节问题 --------- Co-authored-by: longjin <[email protected]>
* 解决设置rust workspace带来的“工具链不一致”的问题 更改workflow
* 调整pcb的sched_info和rwlock，以避免调度器死锁问题 * 修改为在 WriterGuard 中维护 Irq_guard * 修正了 write_irqsave方法 * 优化了代码 * 把 set state 操作从 wakup 移动到 sched_enqueue 中 * 修正为在 wakeup 中设置 running ，以保留 set_state 的私有性 * 移除了 process_wakeup
实现进程退出的逻辑 * 标志进程sleep * 修复wakeup的问题 --------- Co-authored-by: longjin <[email protected]>
* 完成了completion的基本结构，待完善上级调用 * 用SpinLock保护结构体并发安全 * 修改原子变量为u32，修复符号错误 * irq guard * 修改为具有内部可变性的结构体 * temp fix * 修复了由于进程持有自旋锁导致的不被调度的问题 * 对 complete 系列方法上锁，保护 done 数据并发安全 * 移除了未使用的依赖
* 重构显示刷新驱动
* 维护进程树 * 维护进程树 * 更改代码结构 * 新建进程时，设置cwd * 调整adopt childern函数，降低开销 --------- Co-authored-by: longjin <[email protected]>
* PATH * safe init * waitqueue兼容C部分 * waitqueue兼容C部分 * 删除semaphore.c,在ps2_keyboard中使用waitqueue * 删除semaphore.c,在ps2_keyboard中使用waitqueue * current_pcb的C兼容 * current_pcb的C兼容 * current_pcb的C兼容 * fmt * current_pcb的兼容 * 针对修改 * 调整代码 * fmt * 删除pcb的set flags * 更改函数名 --------- Co-authored-by: longjin <[email protected]>
* 能够调通，执行完textui_init * 能跑到initial kernel thread * fmt * 能够正常初始化所有服务（尚未能切换到用户程序） * 删除部分无用的extern * 存在问题：ap处理器启动后，bsp的smp_init函数return之后就出错了，怀疑是栈损坏 * 解决smp启动由于未换栈导致的内存访问错误 * debug * 1 * 1 * lock no preempt * 调通 * 优化代码，删除一些调试日志 * fix
* 维护进程树 * 维护进程树 * 更改代码结构 * 新建进程时，设置cwd * 调整adopt childern函数，降低开销 * wait4 * 删除c_sys_wait4 * 使用userbuffer保护裸指针 --------- Co-authored-by: longjin <[email protected]>

完成了进程管理重构
请注意，这个pr删除了signal相关代码（因为原来的写的太烂了），signal接下来几周将由 @chiichen 在另一个pr补上。
