[Bernd Kuhls]

https://download.gnome.org/sources/libxml2/2.15/libxml2-2.15.3.news

- parser: Pass userData to SAX text callbacks in xmlParseReference (type-confusion)
- entities: copy children in xmlCopyEntity
- c14n: Fix Type confusion in xmlC14NProcessAttrsAxis
- python: Do not decref string after adding to the list (double-free / use-after-free)
- c14n: Reuse tmp_str, xmlStrcat reallocates *cur (double-free)
