implement test_might_fail using a refactored test_must_fail

Add an (optional) first parameter "ok=<special case>" to test_must_fail
and return success for "<special case>". Add "success" as
"<special case>" and use it to implement "test_might_fail". This removes
redundancies in test-lib-function.sh.

You can pass multiple <special case> arguments divided by comma (e.g.
"test_must_fail ok=success,something")
