v4l2: Replace miss-use of crop meta in favour of proper offset
...
This moves away from copying information and store everything inside
the GstVideoInfo structure. The alignement exposed by v4l2 api
is now handled using proper offset.

v4l2bufferpool: Acquire cannot return a buffer from another pool
...
Return a buffer from an otherpool has unwanted side effects that lead to leaks and
prevents deactivating the pool. Instead, we change the _process() API so it can
replace the internal buffer with the buffer from the downstream pool. This implied
moving from _fill() to _create() method in the src.

qbuf/dqbuf.
