Doc: Prepare for building modular QtCore docs.

This change fixes most qdoc errors in QtCore. There are about 900 left.
The main thing this change does is moving documentation from qtcore from
/doc/src to /src/corelib/doc.
Other issues resolved are mis-use of qdoc commands.

+    \title JSON Support in Qt
+    \ingroup qt-basic-concepts
+    \brief An overview over the JSON support in Qt.
+
+    \ingroup frameworks-technologies
+
+    \keyword JSON
+
+    Qt provides support for dealing with JSON data. JSON is a
+    format to encode object data derived from Javascript, but
+    now widely used as a data exchange format on the internet.
+
+    The JSON support in Qt provides an easy to use C++ API to parse,
+    modify and save JSON data. It also contains support for saving this
+    data in a binary format that is directly mmap'able and very fast to
+    access.
+
+    More details about the JSON data format can be found at \l{http://json.org}{json.org}
+    and in \l{http://tools.ietf.org/html/rfc4627}{RFC-4627}.
+
+    \tableofcontents
+
+    \section1 Overview
+
+    JSON is a format to store structured data. It has 6 basic data types:
+
+    \list
+    \li bool
+    \li double
+    \li string
+    \li array
+    \li object
+    \li null
+    \endlist
+
+    Any value can be any of the above type. A boolean value is represented by the
+    strings true or false in JSON. JSON doesn't explicitly specify the valid range
+    for numbers, but the support in Qt is limited to the valid range and precision of
+    doubles. A string can be any valid unicode string. An array is a list of values, and an
+    object is a dictionary of key/value pairs. All keys in an object are strings, and
+    an object cannot contain any duplicated keys.
+
+    The text representation, of JSON encloses arrays in square brackets ([ ... ]) and
+    objects in curly brackets ({ ... }). The different entries in arrays and objects
+    are separated by commas. The separator between keys and values in an object is a
+    colon (:).
+
+    A simple JSON document encoding a person, its age, address and phone numbers could
+    look like:
+
+    \code
+    {
+        "FirstName": "John",
+        "LastName": "Doe",
+        "Age": 43,
+        "Address": {
+            "Street": "Downing Street 10",
+            "City": "London",
+            "Country": "Great Britain"
+        },
+        "Phone numbers": [
+            "+44 1234567",
+            "+44 2345678"
+        ]
+    }
+    \endcode
+
+    The above example consists of an object with 5 key/value pairs. Two of the values are strings,
+    one is a number, one is another object and the last one an array.
+
+    A valid JSON document is either an array or an object, so a document always starts
+    with a square or curly bracket.
+
+    The JSON support in Qt consists of a set of 4 classes.
+
+
+    \section1 The JSON Classes
+
+    The JSON support in Qt consists of these classes:
+
+    \annotatedlist json
+
+    All JSON classes are value based, implicitly shared classes.
