Just fwiw, the STATE_OFF => STATE_PENDING_STREAMON is to properly handle state
change sequence like: PAUSED->READY->PAUSED..

In this case, the buffers are still allocated, but a VIDIOC_STREAMON is needed
in order to start playing again.

so maybe not exactly the same issue as the need to destroy buffers when going
back to NULL state... but a related state change issue.

The _stop_streaming() change should definitely be a different patch... because
I think a few other things are needed to handle renegotiating caps properly. 
(It's something on my TODO list, but haven't gotten too yet.. feel free to file
a bug and assign to me for proper handling of caps renegotiation.)
