Prepare for treating indirect references differently depending on whether we are parsing a PDF file (in which case reference to objects not in the xref table are null even if they are in the object cache) or whether parse from user code (in which case an indirect reference can refer to a user created object).
-
Handle case where named destination is a dictionary with /D entry. Test case is hand-edited outlines-with-old-root-dests.pdf with modified object 107.

Using search and replace.

Use get() and use_count() instead. Add #define NO_POINTERHOLDER_DEPRECATION to remove deprecation markers for these only. This commit also removes all deprecated PointerHolder API calls from qpdf's code except in PointerHolder's test suite, which must continue to test the deprecated APIs.

This change works around STL problems with Embarcadero C++ Builder version 10.2, but std::vector is more common than std::list in qpdf, and this is a relatively new API, so an API change is tolerable. Thanks to Thorsten Schöning <6223655+ams-tschoening@users.noreply.github.com> for the fix.
