In order to do resource recycling we need a table structure. In the search of one, we concluded that a task list will make things easier when we start adding COPY and NEW space handling. This commit is for utcb recycling. Now, it does not support thread trees more than one level depth. Thus, to be able to test it, we preferred l4thread_destroy instead of l4thread_exit.
