posix: Simplify POSIX_API_Control

Return stack area via pthread_getattr_np().

Simplify

* pthread_attr_setaffinity_np(), and
* pthread_attr_getaffinity_np()

and let the scheduler do the more sophisticated error checks.

Make

* pthread_setaffinity_np(),
* pthread_getaffinity_np(),
* pthread_attr_setaffinity_np(), and
* pthread_attr_getaffinity_np()

available in all configurations.

Update #2514.
Close #3145.
Close #3168.
