----------------------------------

Apologies.  The patch I submitted was broken.  I think I may have messed up the state of this
issue :(

> Currently, get_json_object(json_txt, path) always returns null if json_txt is not a JSON
object (e.g. is a JSON array) at the root level.
> I have a table column of JSON arrays at the root level, but I can't parse it because
of that.
> get_json_object should accept any JSON value (string, number, object, array, true, false,
null), not just object, at the root level. In other words, it should behave as if it were
named get_json_value or simply get_json.
