A TranslationUnit is owned by TranslationUnits now. TranslationUnits allows to add another TranslationUnit and to update/query the recently and previously parsed translation unit. This does not change any behavior yet. Change-Id: I8a2f0cc05d3e51bf739dd5d7c4da14b54147f3ab Reviewed-by: David Schulz <david.schulz@qt.io>
