* Issue #471: always create directories with mode 0755, regardless of umask.
* Added a JSON_TOKENER_ALLOW_TRAILING_CHARS flag to allow multiple objects
to be parsed even when JSON_TOKENER_STRICT is set.
+* Split the internal json_object structure into several sub-types, one for
+ each json_type (json_object_object, json_object_string, etc...).
+ This improves memory usage and speed, with the benchmark under
+ bench/ report 5.8% faster test time and 6%(max RSS)-12%(peak heap)
+ less memory usage.
+ Memory used just for json_object structures decreased 27%, so use cases
+ with fewer arrays and/or strings would benefit more.
