Fix integer bounds checking in GNU tar sparse format 1.0 parser

 - Make sure the file actually has that many records before trying
   to read one and fail if not.
 - Use the helper macros for size_t overflow checking instead of
   assuming size_t == uint64_t.
 - Impose a "reasonable" upper bound on the number of data segments
   and insist that there is at least one entry.
