  Modified files:
    sys/kern             kern_mutex.c 
  Log:
  - Add an assertion to panic if one tries to call mtx_trylock() on a spin
    mutex.
  - Don't panic if a spin lock is held too long inside _mtx_lock_spin() if
    panicstr is set (meaning that we are already in a panic).  Just keep
    spinning forever instead.
