Add validation features to json_unpack()

* By default, json_unpack() now checks that all items of arrays and
  objects are unpacked. This is useful for validation.

* Add format specifier '*' to suppress this check for individual
  arrays and objects. '*' must appear as the last format specifier
  before the closing ']' or '}'.
