Fixed three bugs with aux threads and nested locks

Fixes two bugs with nested locks:
1) List of aux threads could become corrupted.
  -- moved modifications to be within scheduler lock.

2) Fixed bad EDF comparison ordering that could lead
to schedule thrashing in an infinite loop.

3) Prevent aux threads from inheriting a priority from
a task that is blocked on a real-time litmus lock.
(since the aux threads can't possibly hold these locks,
we don't have to worry about inheritance.)
