Hi3518E 做region

测试region效果，编译了SDK下region的目录，然后执行如下：

# ./sample_region 1
[SAMPLE_RGN_OverlayProcess]-335: the handle:0,creat success!
[SAMPLE_RGN_OverlayProcess]-335: the handle:1,creat success!
[SAMPLE_RGN_OverlayProcess]-335: the handle:2,creat success!
[SAMPLE_RGN_OverlayProcess]-335: the handle:3,creat success!
[SAMPLE_RGN_OverlayProcess]-335: the handle:4,creat success!
display region to chn success!
handle:1,change point success,new point(x:124,y:64) !

Detach handle:2 from chn success
Detach handle:3 from chn success
