jhb dc85464f48 Fix locking issues with aio_fsync(). ...

- Use correct lock in aio_cancel_sync when dequeueing job.
- Add _locked variants of aio_set/clear_cancel_function and use those
  to avoid lock recursion when adding and removing fsync jobs to the
  per-process sync queue.
- While here, add a basic test for aio_fsync().
