Rewrite "testPerm" helper function used for testing of internal runtime code. It's been renamed to "unitTest" and provides API that is extensible in the future by accepting optional "UnitTestOptions" argument. "test" helper was also removed and replaced by overloaded version of "unitTest" that takes only function argument. "UnitTestOptions" currently supports "perms" and "skip" options, where former works exactly as first argument to "testPerm" did, while the latter allows to conditionally skip tests.
