feat(third_party/lisp/s-xml): Check in sources & derivation

Checked in the sources for this because it is tracked upstream in CVS
and I can't be bothered to deal with that right now.

+;;;; This is a Common Lisp implementation of a very basic XML parser.
+;;;; The parser is non-validating.
+;;;; The API into the parser is pure functional parser hook model that comes from SSAX,
+;;;; see also http://pobox.com/~oleg/ftp/Scheme/xml.html or http://ssax.sourceforge.net
+;;;; Different DOM models are provided, an XSML, an LXML and a xml-element struct based one.
