Use dblatex to build PDF documentation instead of docbook2html and xsltproc
to build HTML instead of docbook2html.  Remove all the index generation
logic, since dblatex and xsltproc handle that automatically.  Remove the
contents of the <index> tag in the source, since neither program requires
there be anything in there.

Remove the style sheets and configuration that were used for docbook2*.
