libfastjson 0.99.9 released

Libfastjson is a new fork of the json-c library, which is optimized for liblognorm processing.

This release provides several changes to libfastjson. Most importantly are the added API objects for fjson_object_get_uint() and fjson_object_array_del_idx(). Also included is a bugfix for a dangling pointer that causes a segfault.

For more details, please refer to the changelog below.

Changelog:
0.99.9 2021-01-26

• add API fjson_object_get_uint()
  Thanks to Janmejay Singh for contributing the patch.
• add API fjson_object_array_del_idx()
  Thanks to Noriko Hosoi for contributing the patch.
• bugfix for dangling pointer that causes segfault
  The other functions assume that the memory is either set to NULL or a valid
  json object. The array_list_del_idx function only moves the elements, but
  does not set the pointer to null, which causes the same pointer to remain
  in the list (outside of arr->length). Then, when array_list_put_idx is
  called, the array_list_expand_internal leaps out, meaning that it has not
  set the indices outside of the requested length to 0. array_list_put_idx
  finds the pointer, tries to free it and a double free will be incurred,
  because the actual element is still in the list.
  Thanks to Michael van der Werve for contributing the patch.
