Subject: [PATCH] include/json: Allow arrays, objects as input to json_array()
 and json_object()

The json_array() and json_object() functions currently can only be used
to construct arrays and objects containing strings and integers.
This commit modifies the functions so that they can also encode objects
and arrays within objects and arrays.
