Updated the documentation building tools to work with a recent linuxdoc-tools package.

Note that this is (and always was) a terrible hack and we really should
replace it with something reasonable which wouldn't need changing every
time linuxdoc-tools evolve.

I also needed to include a patched version of LinuxDocTools.pm, because the
original one explicitly refused to work with a non-linuxdoc DTD. The authors
of linuxdoc recommend to use sgmltools-lite in such cases, but it would mean
rewritting our formatting rules to the DSSSL language which I don't dare to
speak about here :)

+
+LinuxDocTools - SGML conversion utilities for LinuxDoc DTD.
+

+
+  use LinuxDocTools;
+  LinuxDocTools::init;
+  @files = LinuxDocTools::process_options ($0, @ARGV);
+  for $curfile (@files) {
+    LinuxDocTools::process_file ($curfile);
+  }
+
+=head1 DESCRIPTION
+
+The LinuxDocTools package encapsulates all the functionality offered by
+LinuxDoc-Tools. It is used, of course, by LinuxDoc-Tools; 
+but the encapsulation should provide for a simple interface for other users as well.
