- Change killpg1()'s first argument to be a thread instead of a process so
  we can use td_ucred.
- In killpg1(), the proc lock is sufficient to check if p_stat is SZOMB
  or not.  We don't need sched_lock.
- Close some races in psignal().  In psignal() there is a big switch
  statement based on p_stat.  All the different cases are assuming that
  the process (or thread) isn't going to change state out from under it.
  To ensure this is true, just lock sched_lock for the entire switch.  We
  practically held it the entire time already anyways.  This also
  simplifies the locking somewhat and actually results in fewer lock
  operations.
- Allow signotify() to be called with the sched_lock held since psignal()
  now does that.
- Use td_ucred in a couple of places.
