Fix QPDF::tableSize
...
Apply temporary fix to deal with fuzz case 68915.
(Error is an integer overflow which would immediately cause a runtime error
as a result of a call to QInitCQIntC::to_size.)

Fix incorrect handling of invalid negative object ids
...
Fix two errors introduced in #1110 and #1112 . Since
#1110 , encountering the invalid indirect reference #1110
-2147483648 n R produces an integer underflow which, if
undetected, immediately trigger a logic error. Since
#1112 , object -1 0 R may be incorrectly identified as
an earlier generation of itself and deleted,
invalidating a live iterator.
