Don't call QSKIP/QVERIFY outside of test functions.

These macros should only be called inside a test function, otherwise
they cannot abort the test function correctly.  Solve this by making the
helper function return a boolean result (and output a warning on
failure to help with debugging) and verify the return value in each test
function that calls the helper.
