Subject: [PATCH] Initialize sphinx config using application instead of config

Currently sphinx config is initialized using sphinx.config,
however in recent versions of Sphinx, plugin specific parameters
as man_pages for man builder has been moved to the extension
and is not initialized from sphinx.config but using sphinx.application.
This is making man_pages to be empty when using sphinx 1.5 and man
builder is not properly called.

This patch initializes sphinx config using sphinx.application which
works fine with both old and new Sphinx versions.

Closes-Bug: #1674795
