DOCBOOK-APPS: TOC and LOT entries when %page-number-restart% in use

Hi,

Now that we have %page-number-restart% working properly in JadeTex, there
are problems with TOC and LOT entries. They need to be prefixed with their
section number.

Attached is a patch to dbautoc.dsl (Norm's latest version, it might not
apply to what, say, RedHat is shipping).

I have offered it to Norm, but he hasn't replied as yet, so I offer it here
in return for the help provided in the past and likely needed in the future.

Note, I have added an extra variable to dbparam.dsl,
%chapter-title-page-separate%, which you will have to define as #f for
things to work properly.

That is part of some future enhancements I want to put through.
