- Add a pinned count to the thread so that cpu pinning may nest. This is
not in scheduler specific data because eventually it will be required by
all schedulers.
- Implement sched_pin and unpin as an inline for now. If a scheduler needs
to do something more complicated than adjusting the pinned count we can
move this into a function later in an api compatible way.
