系统支持newlib，并且可以与musl-C自由切换 1. 新增newlib支持，适配newlib的预留钩子，针对系统能力适配newlib头文件（补充宏定义，结构体定义，posix能力开关）， 采用标准C与自研posix接口声明与结构体定义混合作为C库 2. 梳理kal的依赖关系，kal作为内核对外提供的标准接口，下属包含cmsis、libc、posix。 cmsis为内核对cmsis接口的支持，libc为内核对三方C库的适配及使用，posix为内核自研提供的posix标准接口。 若采用musl-C，则kal中选取libc/musl,posix共同作为C库对外支持； 若采用newlib-C，则kal中选取libc/newlib,部分posix共同作为C库对外支持。 3. fs整理，components/fs下提供基于posix标准的接口改为内部对外接口，供musl以及newlib切换 适配使用 close: #I4ENQ1 Signed-off-by: arvinzzz <zhaotianyu9@huawei.com> Change-Id: I72eda5ac5499f72c67e800e22b0f39eb288f2b94
