commit 92c61e4ce5cba9a205d54a3387e71cc89409d7d1

    Simplify GVariant reference counting
    
    For (non-public-API) *_to_gvariant, explicitly document that they return
    a floating value, and rely on it in callers to avoid a
    variable/sink/unref combo.
    
    This should not change behavior.
