  Log:
   - Remove setrunqueue and replace it with direct calls to sched_add().
     setrunqueue() was mostly empty.  The few asserts and thread state
     setting were moved to the individual schedulers.  sched_add() was
     chosen to displace it for naming consistency reasons.
   - Remove adjustrunqueue, it was 4 lines of code that was ifdef'd to be
     different on all three schedulers where it was only called in one place
     each.
   - Remove the long ifdef'd out remrunqueue code.
   - Remove the now redundant ts_state.  Inspect the thread state directly.
   - Don't set TSF_* flags from kern_switch.c, we were only doing this to
     support a feature in one scheduler.
   - Change sched_choose() to return a thread rather than a td_sched.  Also,
     rely on the schedulers to return the idlethread.  This simplifies the
     logic in choosethread().  Aside from the run queue links kern_switch.c
     mostly does not care about the contents of td_sched.
  
  Discussed with: julian
  
   - Move the idle thread loop into the per scheduler area.  ULE wants to
     do something different from the other schedulers.

  Tested on:      x86/amd64 sched_{4BSD, ULE, CORE}.
