QPDF::processXRefStream

Change the processed Index array to a vector of <first object, number of
entries> pairs.

Add closure damaged to create damagedPDF exceptions.

Tune processing of subsections.

Tune pointer arithmetic.

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.)

Create set without creation of an intermediate vector.

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.

Change set visited to std::vector<bool>

Swap front and back, and change queue from list to vector

Test for missing object before accessing obj_copier.object_map.

Ensure that links to foreign pages are not broken provided that the page is
subsequently copied.
