[dpdk-dev] [PATCH v2] doc: change sphinx theme to the read the docs theme

[John McNamara <john.mcnamara@intel.com>]

Change the Sphinx default theme from "alabaster" to the ReadTheDocs
theme. See for example:

    http://dpdk.readthedocs.org/en/latest/

This looks better for technical documentation and in particular
it has a 80 char wide verbatim block rendering.

Also turn off option for distracting Html mouseover permalinks.

v2:
* Add version check since rtd theme is only available, by default,
  in Sphinx 1.3.1 and later.
