qpdf 11.
* Perform code cleanup including some source-compatible but not
binary compatible changes to function signatures.
binary compatible changes to function signatures, use of anonymous
namespaces, and use of "= default" and "= delete" in declarations.

@ -479,8 +479,6 @@ This is a list of changes to make next time there is an ABI change.
Comments appear in the code prefixed by "ABI". Always Search for ABI
in source and header files to find items not listed here.
* See where anonymous namespaces can be used to keep things private to
a source file. Search for `(class|struct)` in **/*.cc.
* Having QPDFObjectHandle setters return Class& to allow for
use of fluent interfaces. This includes array and dictionary
mutators.
