LiteOS_a中有部分配置宏进行了重复冗余定义，导致当头文件未被包含时，极易引入错误，
故对menuconfig配置宏进行统一处理，均使用#ifdef/#ifndef作为预编译判断方式

in the liteos_a directory, we used to use `make clean all` command
to build liteos_a kernel for test.

1. 更正makefile过滤时被替换函数的不正确路径
2. 防止LOCAL_SRCS再直接+= /*/*.c添加回来

Liteos_a FATFS需要提供格式化时设置卷标的功能，该功能在当前系统中缺失。
现在恢复该功能，使用方法与原来一致。即使用set_label设置卷标文本后，调用format对设备格式化。

　kill进程时，会将因为liteipc阻塞的线程唤醒，使其调度并自动退出，由于liteipc阻塞机制为
循环阻塞方式，会导致将因liteipc阻塞的线程唤醒后又进入等待中。此处在唤醒因liteipc阻塞的
线程后检查是否已有kill标志，如果有使其按接收数据失败退出，在返回用户态之前，该线程会进
入退出流程，结束运行。

背景：LOS_UserMemClear接口原有实现是通过在内核中
申请一块堆内存并对其清零，调用copy_to_user来达到
对用户态内存清零的目的，需要使用堆内存。
修改方案：基于汇编实现内核对用户态内存清零的功能。

【背景】信号管道用例ItPosixPipe005偶尔会失败，经查找，发现是CPU调度所致，延时时间与期望调度不符合，增加延时时间即可

【修改方案】修复了此问题，但是考虑pipe用例整体不稳定，并且pipe用例的pipe函数存在问题，先暂时下线，等pipe部分全部修改完毕后再上线。

Merge pull request !338 from phchang/rwlock

【背景】修复rwlock门禁用例多次测试出现的程序会卡死在某一个地方的问题，经查找程序会卡在循环里面

【修改方案】
1.经测试，发现用例在创建线程后对退出标志位做了初始化，但卡在循环中不动的原因是在创建线程后立刻发生了调度，没有来得及初始化，则发生了错误，故会出现卡在循环中的情况。
而且，由于卡在循环中时线程是同一优先级，可能不会发生调度，故在循环里面加了一句可以调度的语句，防止在一处循环卡的太久。
2.将该用例挪出门禁，待稳定后恢复。
【影响】
对其它用例无影响。
