[xml] [PATCH] Add methods for python3 iterator

[Ron Angeles <ronangeles gmail com>]

xmlCoreDepthFirstItertor and xmlCoreBreadthFirstItertor only
implement a python2-compatible iterator interface. The necessary
method names (__next__) have been added. They just passthrough
to the python2 method (next).
