dc863a10b2 Change test output file from out.pdf to a.pdf for cleanup 
The cleanup() method automatically removes certain files, but not
out.pdf. Using a.pdf prevents the file from being left behind after
the tests run.

293a2e52b3 Disregard appearance state when irrelevant (fixes #949) 
If /AP is a dictionary of streams rather than a dictionary of
dictionaries, disregard /AS, which is supposed to point to a subkey of
one of the dictionaries. This fix prevents qpdf's annotation
flattening from discarding some annotations when /AS is erroneously
set.

2394acf7a6 Remove explicit direct object check from getObject 
An indirect object reference to 0, 0 is invalid. If it appears in the
file or is parsed from a string, the parser catches it. This check
would only be useful for someone explicitly calling getObject with 0,
0, and that would trigger an error during resolve().

8a3cdfd2af Change QPDFObjectHandle == to isSameObjectAs 
Replace operator== and operator!=, which were testing for the same
underlying object, with isSameObjectAs. This change was motivated by
the fact that pikepdf internally had its own operator== method for
QPDFObjectHandle that did structural comparison. I backed out qpdf's
operator== as a courtesy to pikepdf (in my own testing) but also
because I think people might naturally assume that operator== does a
structural comparison, and isSameObjectAs is clearer in its intent.

c7a4967d10 Change reset to disconnect and clarify comments

dba61da1bf Create a special "destroyed" type rather than using null 
When a QPDF is destroyed, changing indirect objects to direct nulls
makes them effectively disappear silently when they sneak into other
places. Instead, we should treat this as an error. Adding a destroyed
object type makes this possible.

55cc2ab680 Re-introduce QPDFObject.hh as deprecated 
* Just removing a header file would cause build errors with no hint as
  to what happened. This way, people get a warning rather than error
  for the life of qpdf 11, and the warning tells them what to do.

* This avoids build surprises resulting from having two versions of
  QPDF headers installed at once. If you were building code out of a
  checkout of qpdf but had an older version installed on your system,
  if your code included <qpdf/QPDFObject.hh>, everything would work,
  but then your code would break without QPDFObject.hh later.

4f4b908605 Add a file with arrays with lots of nulls to the test suite 
A bug was fixed between qpdf 8.4.2 and 9.0.0 regarding this type of
file (see #305 and #311), but it was necessary to retest after some
major refactoring work at the lexical and parsing layers. This lays
the groundwork for including this in performance benchmarks and in the
qpdf test suite rather than having to keep a large,
non-redistributable file around.

20 arrays of 20K nulls is plenty for performance memory testing and
doesn't take too long to run. Compared to qpdf 8.4.2, in qpdf 11.0.0,
the file generated here uses 3% of the RAM and runs over 4 times
faster.
