  MFC kern_proc.c - fix locking in sysctl_kern_proc()

    Modified files:

    Log:
    Always wire the sysctl output buffer in sysctl_kern_proc() before
    calling sysctl_out_proc().  -- fix from jhb
  
    Move the code in fill_kinfo_thread() that gathers data from struct proc
    into the new function fill_kinfo_proc_only().
  
    Change all callers of fill_kinfo_thread() to call both
    fill_kinfo_proc_only() and fill_kinfo() thread.  When gathering
    data from a multi-threaded process, fill_kinfo_proc_only() only needs
    to be called once.
  
    Grab sched_lock before accessing the process thread list or calling
    fill_kinfo_thread().
