To prevent the motion vector out of range bug, added a motion vector unit test in VP9. In the 4k video encoding, always forced to use extreme motion vectors and also encouraged to use INTER modes. In the decoding, checked if the motion vector was valid, and also checked the encoder/decoder mismatch. The tests showed that this unit test could reveal the issue we saw before.
