Browse Source 
kernel接口融合，添加/修改kernel函数

BREAKING CHANGE:
新增接口：
LOS_TaskResRecycle
LOS_CurrNanosec
LOS_MDelay
接口修改：
LOS_QueueCreate：第一个入参添加const修饰并增加一种异常情况处理
los_memory.c中 OS_ERROR 修改为LOS_NOK，重定义LOS_NOK为（UINT32）-1。
接口位置转移：
LOS_UDelay 由los_task.h/.c 转移到los_tick.h/.c 
宏修改：
LOS_ERRNO_MUX_PEND_INTERR 改名为 LOS_ERRNO_MUX_IN_INTERR
增加宏：
