Implement emulator clock fast-forwarding
When running an unit test, the emulator is sitting in idle task for most
of the time. Since we don't have interrupt support now, the emulator is
just waiting for the next wake-up timer to fire. To save time, we can
actually just figure out which task is the next to wake up, and then
fast-forward the system clock to that time.
With this, all tests run faster and we can remove time-scaling for all
current tests. This improves not only run time but also stability.
If one day we have interrupt support, then we will have to modify this
to take into account the fact that an interrupt might wake a task before
any wake-up timer fires.
BUG=chrome-os-partner:19235
