Fix 695300: don't throw exception on invalid reference number.
Return the null object rather than throwing an exception when parsing
indirect object references with negative object numbers.
Do range check for object numbers (1 .. length) when object numbers
are used instead.
Object number 0 is not a valid object number. It must always be 'free'.
