Eliminate pageout wakeup races.  Take another step towards lockless
vmd_free_count manipulation.  Reduce the scope of the free lock by
using a pageout lock to synchronize sleep and wakeup.  Only trigger
the pageout daemon on transitions between states.  Drive all wakeup
operations directly as side-effects from freeing memory rather than
requiring an additional function call.
