  Log:
  Commit 9/14 of sched_lock decomposition.
   - Attempt to return the ttyinfo() selection algorithm to something sane
     as it has been broken and disabled for some time.  Adapt this algorithm
     in such a way that it does not conflict with per-cpu scheduler locking.
  
  Tested by:      kris, current@
  Tested on:      i386, amd64, ULE, 4BSD, libthr, libkse, PREEMPTION, etc.
  Discussed with: kris, attilio, kmacy, jhb, julian, bde (small parts each)
