    gl/cocoa: keep refs over async operations

    Avoids dereferencing dead objects

    What happens in the autovideosink case is that context 1 is created and
    destroyed before all the async operations hae executed on the associated
    window.  When the delayed operations execute, they then reference dead
    objects and crash.

    We fix this by keeping refs over all async operations so the object
    cannot be deleted while async operations are in flight.
