  Modified files:
    sys/kern             subr_turnstile.c 
    sys/sys              turnstile.h 
  Log:
  - Bring back turnstile_empty() which can check to see if an individual
    queue on a turnstile is empty.
  - Add a turnstile_disown() function that allows a thread to give up
    ownership of a turnstile w/o waking up any waiters.
