>Description:
Omitting "cleanup" from atf_test_case causes cleanup to be missed.
The same happens if "cleanup" is present but tc_cleanup() is missing.
In both cases is it highly likely the test author wanted cleanup
to be run.
>How-To-Repeat:
make mistakes
>Fix:
Flag an error if there is an inconsistency in the test case.
