I'm not a v4l2 expert, but this looks pretty much in line with what the
documentation says.

However, it appears that at least with my pwc cam (Macbook Pro rev. 3 built-in
iSight, ubuntu gutsy) the CAP_TIMEPERFRAME flag is not set, but the ioctls
still work just fine, which would be a driver bug I suppose, but it still
disables functionality that's currently there, so I'm not sure what the best
thing to do is here.
