In the HTML output, this decorates section headers and variable list
terms with a marker ("#") that is a link to the same section/term.
That way, links inside a page can be discovered for easier sharing.
The marker only appears when hovering.
This now requires that all elements that are candidates for such a
link have an id attribute. Otherwise, an error will be generated.
All previously missing ids have been added prior to this patch.

This changes our catalog and view descriptions to use a style inspired
by the new format for function/operator tables: each table entry is
formatted roughly like a <varlistentry>, with the column name and type
on the first line and then an indented description. This provides much
more room for expansive descriptions than we had before, and thereby
eliminates a passel of PDF build warnings.

Make the markup a bit less ad-hoc. A function-table cell now contains
several <para> units, and we label the ones that contain function
signatures with role="func_signature". The CSS or FO stylesheets then
key off of that to decide how to set the indentation. A very useful
win from this approach is that we can have more than one signature
entry per table cell, simplifying the documentation of closely-related
operators and functions.
This patch mostly just replaces the markup in the tables I converted so
far. But I did alter a couple of places where multiple signatures were
helpful.

Jonathan Katz felt that slightly different indentation settings made
for a better-looking result, so sync stylesheet-fo.xsl (for PDF) and
stylesheet.css (for non-website-style HTML) with those choices.

The table layout ideas proposed in commit e894c6183 were not as widely
popular as I'd hoped. After discussion, we've settled on a layout
that's effectively a single-column table with cell contents much like a
<varlistentry> description of the function or operator; though we're not
actually using <varlistentry>, because it'd add way too much vertical
space. Instead the effect is accomplished using line-break processing
instructions to separate the description and example(s), plus CSS or FO
customizations to produce indentation of all but the first line in each
cell. While technically this is a bit grotty, it does have the
advantage that we won't need to write nearly as much boilerplate markup.
This patch updates tables 9.30, 9.31, and 9.33 (which were touched by
the previous patch) to the revised style, and additionally converts
table 9.10. A lot of work still remains to do, but hopefully it won't
be too controversial.
Thanks to Andrew Dunstan, Pierre Giraud, Robert Haas, Alvaro Herrera,
David Johnston, Jonathan Katz, Isaac Morland for valuable ideas.

Turn on the previously disabled automatic scaling of images in HTML
output. To avoid images looking too large on nowadays-normal screens,
restrict the width to 75% on such screens.
Some work is still necessary because SVG images without a viewBox
still won't scale, but that will a separate patch.

Tweak CSS a bit to match latest similar changes to web site style. Also
move some CSS out of the HTML to the stylesheet so that the web site
stylesheet can override it. This should ensure that notes and such are
back to being centered.
Block elements with verbatim formatting (literallayout, programlisting,
screen, synopsis) should be aligned at column 0 independent of the surrounding
SGML, because whitespace is significant, and indenting them creates erratic
whitespace in the output. The CSS stylesheets already take care of indenting
the output.
Assorted markup improvements to go along with it.
