74b6f76872 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.

TEST=Run all tests in parallel for 1000 times.

e71f008388 Put test utility macros in header
Several test utility macros have been duplicated across tests. Let's put
them in a single place.

5007bbc009 Use uintptr_t when converting integer from/to pointer
Perviously we use uint32_t for this, but this doesn't compile for 64-bit
environment (and likely doesn't for 16-bit either.) Use uintptr_t so that
we don't get size mismatch errors.

0a45fa1708 Pthread-based emulator for unit testing
This is the first version of pthread-based RTOS emulator. With this, we
will be able to test high-level modules entirely on the host machine.
