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)
