[PATCH sgml-doctools] Add support for PDF bookmarks in the xorg stylesheet

[Gaetan Nadon]

From: Matt Dew <matt at osource.org>

PDF files can optionally include an active table of contents
that is displayed alongside the pages in the PDF viewer.
These references are called bookmarks.

PDF bookmarks are generated using special functions in each XSL-FO processor
because XSL cannot produce them directly.

No visible problems when building xorg-docs using fop 0.95.
Can you try on some other docs?
I suppose with don't have docs with bookmarks as of yet.
