Stefano Sabatini 6b55aab01a lavfi: create buffer reference in filters which need to access the ref later
Also add internal function ff_null_start_frame_keep_ref().

Fix crash when a following filter (e.g. settb) will unref the reference
passed by start_frame(), and then the reference is accessed in
end_frame() through inlink->cur_buf.
