Right now any ":Field Name: Field Contents" lines end up with significant
padding due to CSS from the "table" CSS which rightly needs padding to
make tables readable. However, field lists don't need this as they tend
to be stacked together. The future heavy use of fields in the parsed
MAINTAINERS file needs this cleaned up, and existing users look better
too. Note the needless white space (and misalignment of name/contents)
between "Date" and "Author":

This patch fixes this by lowering the padding with a more specific CSS.

My eyesight is not in good shape, which means that I have difficulty
reading the online Linux documentation.  Specifically, body text is
oddly small compared to list items and the contrast of various text
elements is too low for me to be able to see easily.

Therefore, alter the HTML theme overrides to make the text larger and
increase the contrast for better visibility, and trust the typeface
choices of the reader's browser.

For the PDF output, increase the text size, use a sans-serif typeface
for sans-serif text, and use a serif typeface for "roman" serif text.

In a code-block with line numbers (option :lineno:) there is a
misalignment of the rendered source code lines on the right side and the
line numbers on the left side.

Since this issue is reported to the RTD theme project, it might be fixed
in the future (take this as a interim solution).

List items with two ore more blocks are not well rendered. E.g. the gap
between last block (l1-b2) of the first list item and the following list
item (L2) is to small::

    * L1 xxxxxxxxxx
      xxxxxxxxxxxxx

      l1-b2 xxxxxxx
      xxxxxxxxxxxxx
    * L2 xxxxxxxxxx
      xxxxxxxxxxxxx

So that it can be read more liquidly, a distance was added to the last
block (l1-b2)::

    * L1 xxxxxxxxxx
      xxxxxxxxxxxxx

      l1-b2 xxxxxxx
      xxxxxxxxxxxxx

    * L2 xxxxxxxxxx
      xxxxxxxxxxxxx

Sphinx is really evil when an older version finds an extra
attribute for the :toctree: tag: it simply ignores everything
and produce documents without any chapter inside!

As we're now using tags available only on Sphinx 1.4.x, we
need to use some creative ways to add a title before the
table of contents. Do that by using a css class.

The layout of (table) captions in the RTD theme is a bit ugly and the
bordered, red colored of inline literals is a bit to gaudy. The
requirements has been discussed in the ML [1].

captions:

  - captions should have 100% (not 85%) font size
  - hide the permalink symbol as long as link is not hovered

inline literal:

  - drop the borderbox and red color

The default table layout of the RTD theme does not fit for vast tables,
like the ones we have in the linux_tv project. This has been discussed
on the ML [1].

The RTD theme is a two column layout, with a navigation column on the
left and a content column on the right:

content column

 RTD theme's default is 800px as max width for the content, but we have
 tables with tons of columns, which need the full width of the
 view-port (BTW: *full width* is what DocBook's HTML is).

table

   - sequences of whitespace should collapse into a single whitespace.
   - make the overflow auto (scrollbar if needed)
   - align caption "left" ("center" is unsuitable on vast tables)
