* More optimizations and cleanup from m-holger (#726, #730)
including major refactor of QPDF's internal representations of
objects. In addition to a large performance improvement, this also
made it possible for QPDFObjectHandle::getOwningQPDF() to return a
null pointer if the owning QPDF had been destroyed. (A more
complete solution to this problem will be introduced for qpdf 12.)
This work also paves the way for a future alternative to
QPDFObjectHandle that is more idiomatic C++ and has greater type
safety.
