Remove the internal copy of JSON-GLib

Browse Source 
The internal copy of JSON-GLib was meant to go away right after the 1.0
release, given that JSON-GLib was still young and relatively unknown.

Nowadays, many projects started depending on this little library, and
distributions ship it and keep it up to date.

Keeping a copy of JSON-GLib means keeping it up to date; unfortunately,
this would also imply updating the code not just for the API but for the
internal implementations.

Starting with the 1.2 release, Clutter preferably dependend on the
system copy; with the 1.4 release we stopped falling back automatically.
The 1.6 cycle finally removes the internal copy and requires a copy of
JSON-GLib installed on the target system in order to compile Clutter.

* #JsonArray is the representation of the array type inside JSON. It contains

*
* Since arrays can be expensive, they are reference counted. You can control

* To append an element, use json_array_add_element().
* To extract an element at a given index, use json_array_get_element().
* To retrieve the entire array in list form, use json_array_get_elements().
* To retrieve the length of the array, use json_array_get_length().

* @short_description: Node in a JSON object model
*
* A #JsonNode is a generic container of elements inside a JSON stream.
* It can contain fundamental types (integers, booleans, floating point
* numbers, strings) and complex types (arrays and objects).
*
* When parsing a JSON data stream you extract the root node and walk
* the node tree by retrieving the type of data contained inside the
* node with the %JSON_NODE_TYPE macro. If the node contains a fundamental
* type you can retrieve a copy of the #GValue holding it with the
* json_node_get_value() function, and then use the #GValue API to extract
* the data; if the node contains a complex type you can retrieve the
* #JsonObject or the #JsonArray using json_node_get_object() or
* json_node_get_array() respectively, and then retrieve the nodes
* they contain.

* SECTION:json-object
* @short_description: a JSON object representation
*
* #JsonArray is the representation of the object type inside JSON. It contains
* #JsonNode<!-- -->s, which may contain fundamental types, arrays or other
* objects. Each member of an object is accessed using its name. Please note
* that the member names are normalized internally before being used; every
* delimiter matching the %G_STR_DELIMITER macro will be transformed into an
* underscore, so for instance "member-name" and "member_name" are equivalent
* for a #JsonObject.
*
* Since objects can be expensive, they are reference counted. You can control
* the lifetime of a #JsonObject using json_object_ref() and json_object_unref().
*
* To add or overwrite a member with a given name, use json_object_set_member().
* To extract a member with a given name, use json_object_get_member().
* To retrieve the list of members, use json_object_get_members().
* To retrieve the size of the object (that is, the number of members it has),
* use json_object_get_size().
