We already enable the parser option to detect invalid UTF-8, but didn't test it. Also, JSON states that behavior of an object with a duplicated key is undefined; we chose to reject it, but were not testing it. With the enhanced tests in place, we can simplify yajl2 initialization by relying on parser defaults being sane. * src/util/virjson.c (virJSONValueFromString): Simplify. * tests/jsontest.c (mymain): Test more bad usage.
