lib: add testing module for UBSAN
This is a test module for UBSAN. It triggers all undefined behaviors
that linux supports now, and detect them.
All test-cases have passed by compiling with gcc-5.5.0.
If use gcc-4.9.x, misaligned, out-of-bounds, object-size-mismatch will not
be detected. Because gcc-4.9.x doesn't support them.
