The Sphinx 1.4.x definition for \DUrole is:

\providecommand*{\DUrole}[2]{%
  \ifcsname DUrole#1\endcsname%
    \csname DUrole#1\endcsname{#2}%
  \else% backwards compatibility: try \docutilsrole#1{#2}
    \ifcsname docutilsrole#1\endcsname%
      \csname docutilsrole#1\endcsname{#2}%
    \else%
      #2%
    \fi%
  \fi%
}

This is broken when it is used inside a \begin{alltt} block.
So, replace it by just "#2", as this won't cause troubles, and
it is one of the fallback methods for it.

This is only one example, demonstrating the benefits of the patch
series.  The CEC_DQEVENT ioctl is migrated to the sphinx c-domain and
referred by ":name: CEC_DQEVENT".

With this change the indirection using ":ref:`CEC_DQEVENT` is no longer
needed, we can refer the ioctl directly with ":c:func:`CEC_DQEVENT`". As
addition in the index, there is a entry "CEC_DQEVENT (C function)".

This reverts commit a88b1672.

From the origin comit log::

  The RST cpp:function handler is very pedantic: it doesn't allow any
  macros like __user on it

Since the kernel-doc parser does NOT make use of the cpp:domain, there
is no need to change the kernel-doc parser eleminating the address_space
tags.

Moved the *duplicate C object description* warnings for function
declarations in the nitpicky mode. In nitpick mode, you can suppress
those warnings (e.g. ioctl) with::

  nitpicky = True
  nitpick_ignore = [
      ("c:func", "ioctl"),
  ]

See Sphinx documentation for the config values for ``nitpick`` and
``nitpick_ignore`` [1].

With this change all the ".. cpp:function:: int ioctl(..)" descriptions
(found in the media book) can be migrated to ".. c:function:: int
ioctl(..)", without getting any warnings. E.g.::

  .. cpp:function:: int ioctl( int fd, int request, struct cec_event *argp )

  .. c:function:: int ioctl( int fd, int request, struct cec_event *argp )

The main effect, is that we get those *CPP-types* back into Sphinx's C-
namespace and we need no longer to distinguish between c/cpp references,
when we refer a function like the ioctl.

Add option 'name' to the "c:function:" directive.  With option 'name'
the ref-name of a function can be modified. E.g.::

    .. c:function:: int ioctl( int fd, int request )
       :name: VIDIOC_LOG_STATUS

The func-name (e.g. ioctl) remains in the output but the ref-name
changed from ``ioctl`` to ``VIDIOC_LOG_STATUS``. The index entry for
this function is also changed to ``VIDIOC_LOG_STATUS`` and the function
can now referenced by::

    :c:func:`VIDIOC_LOG_STATUS`

There are two big tables here that are very hard to adjust its
size.

The first one would fit into one page, but the latex.py logic
at Sphinx auto-switches to longtable when there are more than 30
rows. There's no way to override without coding.

The second one is really big, and won't fit on a single page.
So, it has to use tiny font to fit.

It is painful to put code/verbatim code in bold. It seems that
the only way is to arrange it like:
	``foo``
	    bar

At least on LaTeX output, when this happens, the "foo" string
is not hidentable/breakable. The entire string should fit into
a single line.

Add a workaround for this ReST limitation by splitting the
foo string into two strings, on separate lines. The output
is not the best, but it works.

Sphinx is really pedantic with respect to the order where

The order that seems to work is:
