This allow to parse a string that is not NUL-terminated. With that options disabled, YAJL v2 would look ahead on completion to find out if there is more to parse. YAJL v1 doesn't have this behavior. Any function function that allocate a yajl_handle via this function either parse a NUL-terminated string, or do provide proper length. So change the default and allow garbage (like a different JSON document) after the end of the data to parse. This is importand for the QMP client, as there could be more than one message to parse, and YAJL would consider the next message to be garbage and throw an error.
