Title: Critical section ukernel test
Description:
This test verifies that the microkernel task_offload_to_fiber() API operates as
expected.
This test has two tasks that increment a counter. The routine that
increments the counter is invoked from K_swapper() due to the two tasks
calling task_offload_to_fiber(). The final result of the counter is expected
to be the the number of times task_offload_to_fiber() was called to increment
the counter as the incrementing was done in the context of K_swapper().
This is done with time slicing both disabled and enabled to ensure that the
result always matches the number of times task_offload_to_fiber() is called.

Building and Running Project:
This microkernel project outputs to the console. It can be built and executed
on QEMU as follows:
make pristine
make microkernel.qemu
If executing on Simics, substitute 'simics' for 'qemu' in the command line.
