Threads must be joined on scheduler termination and tasks must be pushed onto the stack to allow better memory management.

This seems to be only possible with two different function names, as variadic arguments and default arguments wont work together.

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

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.

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).

This will be used for storing thread tasks aligned in continous memory, allowing different theads to work on the data without interfearing.

This requires the user to explicitly manage the storage duration/place of the thread local state, making a fine grained memory allocation simpler.

The local storage per thread is only a pointer, this must be assigned AFTER the local storage object has moved to it's final location (e.g. on the stack of the caller). We might even change this a little further in the future to make the location of the state object more transparent.

Seperate library from other parts of project (samples, playground, testing, ...). We still are in one 'toplevel' cmake project, so we can for exmaple compile everything (library and playground) in debug mode, for simple development.
