Added code submitted by Andreas Pakulat to provide node equality,
* python/libxml.c, python/libxml.py, python/tests/compareNodes.py,
python/tests/Makefile.am:
Added code submitted by Andreas Pakulat to provide node
equality, inequality and hash functions, plus a single
test program to check the functions (bugs 345779 + 345961).
