rework set_thread_limit()

- allow calling set_thread_limit() more than once by reinitializing the
TBB task_scheduler
- always call set_thread_limit() using static initialization before any
user code (and thus TBB usage) happens
- as a result DEAL_II_NUM_THREADS will now always be respected even if
users never call set_thread_limit() themselves
- test suite: always enforce a maximum of 5 threads (instead of only if
not configured with MPI)
- add test for changing the thread limit

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
