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.
