reactivated xsltMatchPattern() since this is really something one may want

* libxslt/pattern.[ch] doc/libxslt-api.xml doc/libxslt-refs.xml:
  reactivated xsltMatchPattern() since this is really something
  one may want to have access to in an extension function.
* Makefile.am configure.in python/Makefile.am python/generator.py
  python/libxml_wrap.h python/libxsl.py python/libxslt-python-api.xml
  python/libxslt.c python/libxslt_wrap.h python/libxsltclass.txt
  python/types.c: started working on the python bindings, borrowed
  most of the work done for libxml2, most of the generator code
  is similar. Commit at the point where this compiles cleanly and
  "import libxslt" doesn't yield any missing entry point.
