The original titles only had the module name, which is not very useful
when scanning the list. By adding a very brief description to each
title, the table of contents becomes friendlier.
Also amend the introduction in the "additional modules" appendix, using
the word "Extension" more extensively. Nowadays, almost all contrib
modules are extensions, so this is also helpful.

Three parameters have been using "int" rather than "integer" to describe
their type:
auth_delay.milliseconds
max_logical_replication_workers
pg_prewarm.autoprewarm_interval
This is inconsistent with any other integer GUCs listed in the docs
(148, as far as I can see).

Since some preparation work had already been done, the only source
changes left were changing empty-element tags like <xref linkend="foo">
to <xref linkend="foo"/>, and changing the DOCTYPE.
The source files are still named *.sgml, but they are actually XML files
now. Renaming could be considered later.
In the build system, the intermediate step to convert from SGML to XML
is removed. Everything is build straight from the source files again.
The OpenSP (or the old SP) package is no longer needed.
The documentation toolchain instructions are updated and are much
simpler now.

For DocBook XML compatibility, don't use SGML empty tags (</>) anymore,
replace by the full tag name. Add a warning option to catch future
occurrences.
Alexander Lakhin, Jürgen Purtz
The main problem is that DocBook SGML allows indexterm elements just
about everywhere, but DocBook XML is stricter. For example, this common
pattern
<varlistentry>
<indexterm>...</indexterm>
<term>...</term>
...
</varlistentry>
needs to be changed to something like
<varlistentry>
<term>...<indexterm>...</indexterm></term>
...
</varlistentry>

There is currently nothing in the build system that enforces that things
stay valid, because that requires additional tools and will receive
separate consideration.
This variable provides only marginal error-prevention capability (since
it can only check the prefix of a qualified GUC name), and the consensus
is that that isn't worth the amount of hassle that maintaining the setting
creates for DBAs. So, let's just remove it.
With this commit, the system will silently accept a value for any qualified
GUC name at all, whether it has anything to do with any known extension or
not. (Unqualified names still have to match known built-in settings,
though; and you will get a WARNING at extension load time if there's an
unrecognized setting with that extension's prefix.)
There's still some discussion ongoing about whether to tighten that up and
if so how; but if we do come up with a solution, it's not likely to look
anything like custom_variable_classes.
