Hacking, mostly on the output support:

- libxslt/xslt.c: added support for disable-output-escaping
  will need libxml version > 20211
- libxslt/transform.c: cleanup
- libxslt/xsltutils.[ch]: added output functions
- libxslt/xsltproc.c: reuse the output function
- tests/REC2/Makefile.am tests/REC2/vrml.xml: added VRML output test
