libgui: Make IGraphicBufferConsumer a SafeInterface

    // This is explicitly *not* the actual signature of IGBC::releaseBuffer, but:

    //     1) We have no easy way to send the EGL objects across Binder

    //     2) This has always been broken, probably because

    //     3) IGBC is rarely remoted

    // For now, we will choose to bury our heads in the sand and ignore this problem until such time

    // as we can finally finish converting away from EGL sync to native Android sync

    // and when that consumer disconnects the BufferQueue is placed into the "abandoned" state,

    // causing most interactions with the BufferQueue by the producer to fail. controlledByApp
