1bf0907b59 [media] pixfmt-nv12mt.rst: use PNG instead of GIF
pdflatex doesn't like gif images:
	None:None: WARNING: no matching candidate for image URI u'media/uapi/v4l/pixfmt-nv12mt_files/nv12mt.*'
	None:None: WARNING: no matching candidate for image URI u'media/uapi/v4l/pixfmt-nv12mt_files/nv12mt_example.*'

But it works fine with png. So, convert them. As a plus, PNG images
are smaller.

44f4ddd1bf Merge branch 'xelatex' into doc/4.9
Mauro says:

	This patch series fix Sphinx to allow it to build the media
	documentation as a PDF file.

	The first patch is actually a bug fix: one of the previous patch
	broke compilation for PDF as a hole, as it added an extra
	parenthesis to a function call.

	The second patch just removes a left over code for rst2pdf.

	The other patches change from "pdflatex" to "xelatex" and address
	several issues that prevent building the media books.

	I think this patch series belong to docs-next. Feel free to merge
	them there, if you agree. There's one extra patch that touches
	Documentation/conf.py, re-adding the media book to the PDF build,
	but IMHO this one would be better to be merged via the media tree,
	after the fixes inside the media documentation to fix the build.

Currently, CPUIDLE_STATE_MAX has been defined as 10 in the cpuidle head file,

Looks like rst2pdf is not robust enough, especially for large documents.

Use recursive make on the Sphinx generated makefile to convert latex to
pdf. The ugly detail is that pdf is generated into
Documentation/output/latex.

Unfortunately, the pdflatex build generates huge amounts of build log
noise, and also fails in the end. We'll fix that next.
