Turn around the spinlock code to reduce the chance of programmer error.
Remove spin_lock_crit() and spin_unlock_crit().  Instead make the primary
spinlock API, spin_lock() and spin_unlock(), enter and exit a critical
section.  Add two API functions, spin_lock_quick() and spin_unlock_quick()
which assume the caller is already in a critical section or that the spinlock
will never be used by a preempting thread (hardware interrupt or software
interrupt).
