Please note that this does currently not execute, but only removed the 'old aspecs'. We are still missing launching the root fork_join task.

This is required to correctly execute multiple, consecutive wait_for_all calls in one fork_join_sub_task.

This resulted from an merge gone wrong.

These currently do nothing but being boilerplate required to implement a new top level task.

The __thread implementation of thread local, static variables seems more efficient, so we activate this by default. If it is (for some reason) not available/slower than the pthread version, one can toggle it for the specific system/processor later on using macros.

We do this to properly separate the cache alginment logic in the next step, allowing us to port all cache aligned objects without worrying about portability.
