[bug#61015] [PATCH core-updates 0/9] Modernize and fix docbook-xml

[Bruno Victal]

This patch-series modernizes docbook-xml package definitions and
properly patches the catalog.xml paths using XSLT.
I've used XSLT here as it seems easier (and better documented)
to perform XML operations with it. I did a small prototype with
(sxml transforms) but due to guile-bug #20339, it's impossible to go
from sxml->xml, ruling it out from being a suitable replacement for XSLT.

The situation for docbook-xml-4.1.2 could be considered extraordinary
since it's the only package that doesn't come with a catalog.xml file,
requiring a pre-built one to be used. (It can be generated from source,
by implementing a (PEG) parser for SGML catalogs but this seems
unnecessary for a file that is unlikely to see any changes.)

With these changes, it's no longer required for packages to do
substitute* or other workarounds to coerce docbook-xml
to play nicely, libxml2 will automatically find the DTDs
through its native-search-path. (XML_CATALOG_FILES variable)

A good follow-up to this patch-series would be to search and destroy
the workarounds currently employed by docbook-xml dependant packages
to discourage cargo-culting redundant procedures.
