    fate: cover MJPEG restart markers with one macroblock column

    Encode two 16x160 frames with two slices to cover internal row boundaries, slice endings, restart-number wraparound and omission of a marker after the final row. Check the encoded packets with framecrc so decoder tolerance cannot hide incorrect markers. Use the existing testsrc2 source, integer DCT and a reference under tests/ref/fate.
