Now, I understand. so I can just move tst_check_cmd declaration into 
tst_private.h and then tst_test.c included it.

But the source code should move into where, it has two choices:
1) like v1, move a new lib source file ie tst_version_parser.c
2) since it is related to cmd, we can move it into lib/tst_cmd.c


I prefer to use 2nd way. What do you think about this?
