 - xmlreader: propagate reader resource loaders to validator parsers
 - python: Make python bindings python2 compatible
 - xmlregexp: Fix escape-sequence character range matching
 - xmlreader: Free input in xmlReaderForFd (memory-leak)
 - xmlstring: Free cur on every error for xmlStrncat (memory-leak)

 - dist: Add generated documentation to the dist as "dist-doc" folder
   to simplify downstream packaging of doc
 - Fix xmlRemoveEntity removing from wrong hash table
 - use duplicating variant in relaxng to mitigate UAF
 - Fix memory leak in xmlTextWriterStartAttributeNS on OOM
