Get rid of bitmap images

The goal of this patch series is to get rid of PNG images, using either graphviz or SVG for images.

For old images generated with xfig, stored inside PDF, just convert them to SVG and cleanup the images using inkscape.

Other images need to be rewritten in SVG.

The pipeline image is actually a graphviz diagram. So, use dot to convert it to SVG.

For now, I'm keeping the image conversion rules inside the Documentation/media/Makefile. As we get other docs using images, the best would be to move those rules to Documentation/Makefile.sphinx, while we don't have a Sphinx extension or fixup that would handle them directly.

NOTE: some images use more than 998 columns, causing troubles with some MTA and MUA that could refuse them, because of an IETF RFC 2821 violation:

	$ git send-email patches/tmp
	fatal: patches/tmp/0001-media-convert-more-media-images-to-SVG.patch: 191: patch contains a line longer than 998 characters

Due to that, in case you miss a patch, I'm also storing them on my development tree at:
https://git.linuxtv.org/mchehab/experimental.git/log/?h=svg-images

It is based on docs-next tree.
