    decklinksrc: Handle callback/delegate object the same way as in the sink

    Potentially fixes crashes.

    decklinksink: Don't crash when going to READY another time

    We have to handle the callback object a bit different:
    a) it needs a virtual destructor
    b) we need to set the callback to NULL when we're done with the output
    c) create a new one every time
