  Log:
   - Add an integer argument to idle to indicate how likely we are to wake
     from idle over the next tick.
   - Add a new MD routine, cpu_wake_idle() to wakeup idle threads who are
     suspended in cpu specific states.  This function can fail and cause the
     scheduler to fall back to another mechanism (ipi).
   - Implement support for mwait in cpu_idle() on i386/amd64 machines that
     support it.  mwait is a higher performance way to synchronize cpus
     as compared to hlt & ipis.
   - Allow selecting the idle routine by name via sysctl machdep.idle.  This
     replaces machdep.cpu_idle_hlt.  Only idle routines supported by the
     current machine are permitted.
