背景：
    调度、线程、软件定时器、sortlink、percpu、异常、workqueue模块相互耦合，存在很多不属于本模块的实现，
导致这几个模块间依赖混乱、且到处引用其它模块的内部成员。

方案描述：
    解决上述依赖混乱的问题，为后续调度框架打基础，优化后依赖关系：

                                                              | ---> los_swtmr_pri.h --> workqueue
los_sortlink_pri.h: ---> los_sched_pri.h --> los_task_pri.h -->
   作为基础算法                                               | ---> ipc
(现在为双向链表),
做到功能最小化，
便于后续其它算法替换

调度框架大体方案描述：

1.cpu run queue ----> 任务延时队列

                                         |---- 调度队列
                   |----  EDF        --->
                   |                     |---- 方法(Delay、Suspend、Resume、EntReadyQue、Exit等)
                   |
                   |                     |---- 调度队列
2.task ---> 调度策略----> SCHED_RR   --->
                   |                     |---- 方法(Delay、Suspend、Resume、EntReadyQue、Exit等)
                   |
                   |                     |---- 调度队列
                   |----> SCHED_IDLE --->
                                         |---- 方法(Delay、Suspend、Resume、EntReadyQue、Exit等)

1. 原kernel/common目录下属于内核拓展组件，统一移入kernel/extend管理
2. Kconfig分层，各模块自己的配置放到自己目录下管理
3. 原platform下不属于平台的公共代码抽到kernel/common下，只留板级链接脚本和一些编译脚本指向device目录下触发平台相关的编译
4. 对外公共头文件统一抽到对外include路径
5. 废弃宏，头文件清理

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

BSD compatibility is not optional for the kernel to build, however
platform dependent portion of this configuration, machine_resource_init(),
which is called by nexus_init() is implemented only in the platform
specific library for HiSilicon chips (libhi35xx_bsp.a).
Workaround lack of this library, so that the kernel can be built
for other platforms as well, by excluding it from the compilation.

This change should be removed as soon as the appropriate function
is implemented for other platforms.

During LiteOS consolidation, system_init.o object that contains
SystemInit() doesn't exist yet as it is being built later
and linked in ./vendor directory when OHOS_Image is created.
This is not the case when building for HiSilicon platforms as
SystemInit is provided for them in precompiled libraries.

Workaround this issue by creating "weak" function in LiteOS
that will be replaced by the "strong" symbol from ./vendor
in linking phase of the OHOS_Image.
