I still like the idea to have VIDEO_DQBUF look at O_NONBLOCK and then
either block or return -EAGAIN like read() does.

Done. Also created a new "enum v4l2_buf_type" and renamed
VIDIOC_ENUM_PIXFMT to VIDIOC_ENUM_FMT. Deleted VIDIOC_ENUM_FBUFFMT, you
can do that using VIDIOC_ENUM_FMT + the new type field now.
