实现内核日志系统 (#489)
* 实现写日志和读取日志,并且能够在用户态下执行dmesg命令查看日志 * 通过klogctl实现dmesg * 改用ConstGenericRingBuffer作内核缓冲区 * 更改缓冲区容量 * 将能够输出到控制台的日志级别改为日志级别枚举类,使用SpinLock控制KMSG,使用枚举类定义SYSLOG_ACTION,将do_syslog系统调用接口放在syscall.rs * fix warning * 完善do_syslog注释 * 将KMSG接入kinfo、kdebug等 * fix warning * 修复显示的秒数不正确,·以及无法通过CI的问题
