Add qjson* implementation files from corelib/json
to the qmake build. Add a read-only compile mode,
enabled by defining QT_JSON_READONLY.
Add qmake built-in function parseJson(file, into)
which parses a json file into the given variable.
qmake uses a flat key -> value-list implementation
for storing variables, which means that some hackery
is need to represent arbitrarily nested JSON. Use a
special "_KEYS_" variable for arrays and objects:
Arrays:
["item1", "item2"]
$${array._KEYS_} -> 0 1 2
$${array.0} -> "item1"
$${array.1} -> "item2"
Objects:
{ "key1" : "value1", "key2" : "value2" }
$${object._KEYS_} -> key1 key2
$${object.key1} -> value1
$${object.key2} -> value2
