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.

We do so by pulling out the profiling macros in our own iclude file. In the future we might even be able to use this to build up further visualisations of the executing programm.

Use only placement new on pre-allocated memory. This makes sure that we have to have no assumptions on the inital state of the memory region.

This lead to some bug-fixes that covered move constructors not correctly assigning memory. We might clean this up further by only allowing in place creation of these types (placement new).

There are serval ways we could optimize the calls, but for now this should be enough for first tests.
