- Add a td_pflags field to struct thread for private flags accessed only by

  curthread.  Unlike td_flags, this field does not need any locking.
- Replace the td_inktr and td_inktrace variables with equivalent private
  thread flags.
- Move TDF_OLDMASK over to the private flags field so it no longer requires
  sched_lock.
