Replace malloc_is_system_state_OK() with _Malloc_System_state() to allow early allocations, e.g. in bsp_start(). Here the _Thread_Executing is NULL, thus an _API_Mutex_Lock() would lead to a NULL pointer access. Move malloc() support code to general case rtems_heap_allocate_aligned_with_boundary(). Use rtems_heap_allocate_aligned_with_boundary() to avoid duplicated code.
