    nmalloc - Fix depot race - this should fix remaining issues with firefox.
    
    * nmalloc was accidently calling the libc _pthread_spin_lock() stub
      even when threaded, causing all depot operations to race.  No actual
      lock was being acquired.
    
      Change it over to the internal _SPINLOCK() API.
    
    * Expand libthread_xu's base spinlocks from 128 to 256 and use those
      for the depot lock.  Note that the depot[] array can be upwards of
      80 elements so lets not take any chances.
