+	* Add QPDFObjectHandle::newReserved to create a reserved object
+	and QPDF::replaceReserved to replace it with a real object.
+	QPDFObjectHandle::newReserved reserves an object ID in a QPDF
+	object and ensures that any references to it remain unresolved.
+	When QPDF::replaceReserved is later called, previous references to
+	the reserved object will properly resolve to the replaced object.
