When stop_streaming is called while a frame is currently being retrieved, the
buffer being filled will still be returned with BUF_STATE_DONE. By resetting
the sequence number and checking before returning the buffer, it can now
correctly be returned with BUF_STATE_ERROR.

Add missing functions to query the single fixed frame size (960x540) and

rate up to 60 FPS, as it is polled and not interrupt-driven. For now, we
just report 30 and 60 FPS, which is sufficient to make most V4L2 tools work.

[media] reduce poll interval to allow full 60 FPS framerate
The SUR40 hardware can deliver images at up to 60 FPS; at full USB2 bandwidth,
one raw frame will take about 11 ms to transmit. If the poll interval is above
5 ms, fully handling one frame will take longer than 16 ms and the overall
frame rate will drop below 60 FPS. To get the full frame rate without blocking
all the time and still allowing for a bit of timing jitter, we reduce the poll
interval to 4 ms.

this source has not been updated because it is broken since the very
