Let's be friendly in what we accept: whenever we define a JSON structure, let's also allow decimal strings where we want an integer. This patch purely replaces JSON_VARIANT_UNSIGNED by _JSON_VARIANT_TYPE_INVALID in the various JsonDispatch[] tables, so that we'll happily accept any type in json_dispatch(), so that json_dispatch_uint64() and related tools can do their thing. This does not switch over OCI (as a JSON structure not defined by us).
