This patch makes the framework verify not only the result but also
the execution order of the tests. It also allows each test to
specify expected return code and strings printed by TH and DUT.
The final test results depends on the return code and the expectation.
Therefore, the output now includes 'RESULT' column showing PASS or FAIL:
test name TH_RETURN_CODE DUT_RETURN_CODE TH_STR DUT_STR RESULT
test_task_switch SUCCESS SUCCESS 1 1 PASS
test_task_priority SUCCESS FAILURE 1 1 FAIL
test_stack_overflow DID_NOT_END DID_NOT_END 1 1 PASS
Additionally, this patch:
* Adds CTS_RC_DID_NOT_START and CTS_RC_DID_NOT_END to indicate whether
the test did start or end, respectively.
* Makes stack overflow test check whether stack overflow was detected
and reboot occurred
* Removes post_corruption_test and conflict test since now
the test results are stricly compared against expected results.
* Fixes gpylint errors.

The timer test checks the accuracy of the internal timer. After sync,
DUT and TH start counting down one second. After one second, DUT raises
GPIO level. TH determines whether the test passes or not based on how
much more or less time elapsed than one second, assuming its clock is
calibrated.
This test takes advantage of TH running on a bare chip. If the host
were measuring (instead of TH), the timing would be affected by many
software and hardware layers (e.g. UART drivers on DUT and host,
python interpreter, etc.).
