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.
