cleanup always use stdout if output is NULL don't close filedescriptors

* Makefile.am: cleanup
* debugXML.c: always use stdout if output is NULL
* xmlIO.c: don't close filedescriptors passed to outputBuffers
* python/Makefile.am python/generator.py python/libxml2class.txt
  python/libxml_wrap.h python/types.c: augmented the number of bindings
  handling FILE * and XPath contexts
* python/tests/Makefile.am: avoid a stupid problem due to the
  use of TEST.
