Log Message:
Cleanup/rework cpu_switch*, switch_exit, Idle routine.  Remove pcb_psl
since it was write-only.  When setting up a process, make sure the fake
callframes are properly linked together.

Only lower SPL when in Idle loop.  Raise spl to previous level (which would
be IPL_SCHED) when exiting Idle loop.  Never lower SPL anyplace else.
