  Modified files:
    sys/kern             kern_spinlock.c 
  Log:
  - Randomize spinlock exponential backoff value, which reduces the chance of
    serious spinlock contention (probably) caused by same backoff steps
  - Ktr spinlock backoff value and backoff failure
  - Under debug sysctl tree, add sysctl node for spinlock backoff limit
  - Break long lines
