Changelog:
v2: - Made V4L2_BUF_FLAG_*FRAME flags mandatory [3] and dropped reading
of raw bitstream from the driver code, as was suggested by
Nicolas Dufresne.

- Ran v4l2-compliance [4] and fluster [5][6] tests, like was suggested by
Nicolas Dufresne. Fixed minor v4l2-compliance errors that were related
to a partial initialization of the coded format and were harmless in
practice, but made compliance checker unhappy.
