  Modified files:
    sys/fs/procfs        procfs_ctl.c 
  Log:
  - Change procfs_control()'s first argument to be a thread pointer instead
    of a process pointer.
  - Move the p_candebug() at the start of procfs_control() a bit to make
    locking feasible.  We still perform the access check before doing
    anything, we just now perform it after acquiring locks.
  - Don't lock the sched_lock for TRACE_WAIT_P() and when checking to see if
    p_stat is SSTOP.  We lock the process while setting p_stat to SSTOP
    so locking the process is sufficient to do a read to see if p_stat is
    SSTOP or not.
