Support V4L stateless video decoder API by NVIDIA Tegra decoder driver.
Tested using GStreamer [1] and libvdpau-tegra [2][8].
[1] https://github.com/grate-driver/gstreamer/commit/b8509bdb...
[2] https://github.com/grate-driver/libvdpau-tegra/commit/f82...
[8] https://github.com/grate-driver/libvdpau-tegra/commit/80d...
Changelog:
v3: - Added new decode_params flags [7] instead of V4L2_BUF_FLAG_*FRAME flags,
as was suggested by Nicolas Dufresne.
[7] https://github.com/grate-driver/gstreamer/commit/c5cd847f...
- Added new patch that removes legacy UAPI.
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.
[3] https://github.com/grate-driver/gstreamer/commit/aee292f0...
- 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.
