此MR是为XiUOS增加cortex-m0支持，由上海交通大学IPADS实验室提交。

增加
xiuos\Ubiquitous\XiUOS\board\cortex-m0-emulator 文件夹

修改了 xiuos\Ubiquitous\XiUOS 文件夹下的 path_kernel.mk and Makefile

把
xiuos/Ubiquitous/XiUOS/arch/arm/shared文件夹中armv7-m（cortex-m3、m4、m7均是armv7-m架构）的代码拿出来作为单独文件夹，并且添加armv6-m文件夹（cortex-m0是armv6-m架构)

编译命令
make BOARD=cortex-m0-emulator menuconfig
make BOARD=cortex-m0-emulator

运行命令
qemu-system-arm -machine microbit -nographic -kernel build/XiUOS_cortex-m0-emulator.elf

另：
修复

XiUOS原本HwInterruptcontextSwitch等函数的bug：未保存和恢复callee-save registers。之前的代码未触发该bug，如果在shell中增加register变量，已验证可以触发。

修复

读取方向键等组合字符的BUG。

此次修改基于 wang_weigen_master
