[PATCH] DocBook: Use xmlto to process the DocBook files.

xmlto uses standared XSLT templates to generate manpages, (x)html pages, and
XML FO files which can be processed with passivetex.  This is much faster than
using jadetex for everything.  This patch also reduces the number of
kernel-specific scripts that are needed to generate documentation.
