bufferpool: Add method and virtuals to set flushing state

Here's the implementation. I've ported v4l2 code to test it, without porting
GstBaseSrc to make sure it's backward compatible. It solve many race I was
seeing in v4l2 as the flushing is not handle in sync with the pool state (and
with the pool state lock). Still need to implement few unit tests, though I'm
posting it to gather comments.
