The first two patches simplify the function to find buffers based on a
timestamp: the current code only considered DONE and DEQUEUED buffers,
but that is unnecessarily restrictive.
The next two patches keep dmabuf-based buffers mapped when they are
dequeued. This avoids having to re-map them if they are referenced as key
frames in a stateless codec. This patch has been in use by ChromeOS for
quite some time and it makes sense.
It is more efficient in general anyway since you don't want to have to
map a dmabuf every time you queue it if there is no need for it.
The final 5 patches fix the sole remaining v4l2-compliance bug vivid and
vimc for output field handling in requests.

Hans
