The lack of mjson_next() prevents to iterate easily and need to hack by iterating on a loop of snprintf + $.field[XXX] combined with mjson_find(). This reintroduce mjson_next() so we could iterate without having to build the string. The patch does not reintroduce MJSON_ENABLE_NEXT so it could be used without having to define it.
