The read/write implementation in vb2 reuses existing vb2 functions, but it sets q->fileio to NULL before calling them in order to skip the 'q->fileio != NULL' check. This works today due to the synchronous nature of read/write, but it 1) is ugly, and 2) will fail in an asynchronous use-case such as a thread queuing and dequeuing buffers. This last example will be necessary in order to implement vb2 DVB support. This patch removes the hack by splitting up the dqbuf/qbuf/streamon/streamoff functions into an external and an internal version. The external version checks q->fileio and then calls the internal version. The read/write implementation now just uses the internal version, removing the need to set q->fileio to NULL.
