[GSoC] Progress Report of POSIX Compliance Test Suite

[Cui Xiang]

The structure of fstest with 2 test cases now seems like below

function "void test(void)"

I use chroot to help structure the fstest, so in every single test,
test sees the empty root. The framework are not stable right now, any
suggestion is welcomed.

The tests between file system will be added in the future.
