Bring in the sphinxification of the sound documentation.

Bring in -rc4 patches so I can successfully merge the sound doc changes.

kernel-doc supports documenting struct members "inline" since
a4c6ebed ("scripts/kernel-doc Allow struct arguments documentation
in struct body"). This requires the inline kernel-doc comments to have
the opening and closing comment markers (/** and */ respectively) on
lines of their own, even for short comments. For example:

	/**
	 * struct foo - struct documentation
	 */
	struct foo {
		/**
		 * @bar: member documentation
		 */
		int bar;
	};

Add support for one line inline comments:

	/**
	 * struct foo - struct documentation
	 */
	struct foo {
		/** @bar: member documentation */
		int bar;
	};

Note that mixing of the two in one doc comment is not allowed; either
both comment markers must be on lines of their own, or both must be on
the one line. This limitation keeps both the comments more uniform, and
kernel-doc less complicated.

While the {READ,WRITE}_ONCE() macros should be used in preference to
ACCESS_ONCE(), the circular buffer documentation uses the latter
exclusively.

To point people in the right direction, and as a step towards the
eventual removal of ACCESS_ONCE(), update the documentation to use
READ_ONCE(), as ACCESS_ONCE() is only used in a reader context in the
circular buffer documentation.

There were a few manuals that weren't being built in PDF format, but
there's no reason not to...
Signed-off-by: Jonathan Corbet <corbet@lwn.net>

Mauro says:

This series address a series of errors during PDF generation from
media documentation.

The first patch fixes the late redefinition of a LaTeX command at the
Sphinx LaTeX style that causes build to break when some cross-references
are used.

The next two patches fix PDF output issues with subdev-formats.rst.

The next 3 patches fix image includes and their output for PDF.

It is aligned with Linus request of not having binary-generated images
from their SVG source codes.

I still intend to move the remaing PNG images to vectorial ones (SVG),
as image scale works better, but this will require some additional work.
When done, I'll submit as a separate patch series.

It should also be noticed that the last patch violates the output dir,
when make is used with "O=some_dir", as Sphinx doesn't accept
image files outside the source directory. We'll likely need some Sphinx
extension in order to fix it, but at least with this series (plus Jani Nikola's
PDF fix series), the PDF output should work fine again.

[jc: added a commit fixing up a "make cleandocs" warning]

Recent Makefile changes added an rm command without the requisite "-f",
leading to warnings if the files do not exist.  Make it be quiet again.

The PDF files that contain media images were actually generated
offline from their SVG or PNG source files.

Sphinx can handle PNG sources automatially. So, let's just
drop their PDF counterparts.

For SVG, however, Sphinx doesn't produce the right tags to
use the TexLive SVG support. Also, the SVG support is done via
shell execution, with is not nice.

So, while we don't have any support for SVG inside Sphinx
core or as an extension, move the logic to build them to Makefile,
producing the PDF images on runtime.

NOTE: due to the way Sphinx works, the PDF images should be
generated inside the Kernel source tree, as otherwise Sphinx
won't find it, not obeying what's specified by "O=" makefile
parameter.

PDF build on Kernel 4.9-rc? returns an error with Sphinx 1.3.x
and Sphinx 1.4.x, when trying to solve some cross-references.

The solution is to redefine the \DURole macro.

However, this is redefined too late. Move such redefinition to
LaTeX preamble and bind it to just the Sphinx versions where the
error is known to be present.

Tested by building the documentation on interactive mode:
	make PDFLATEX=xelatex -C Documentation/output/./latex
