[PATCH 0/5] Sphinx reproducibility update

[Leo Famulari <leo@famulari.name>]

Since version 1.4.0, Sphinx has respected the SOURCE_DATE_EPOCH
environment variable for the timestamps it puts in generated
documentation [0].

This patch series updates Sphinx to the latest version, 1.4.4, and
provides all the new dependencies. The final commit in the series
requires the new Sphinx.

Why propagate pytz and snowballstemmer? Otherwise, many packages that
use Sphinx started failing due to pytz or snowballstemmer not being
avaiable. Rather than provide pytz and snowballstemmer to all those
packages, I propagated them from Sphinx itself. I can add pytz and
snowballstemmer to the Sphinx users if desired.

With this change, many Python 2 packages will become reproducible, at
least on a single machine; the only thing holding them back was the
manpage timestamps.

These changes will require 142 rebuilds, mostly of Python packages, but
also of libreoffice (libreoffice seems to depend on *everything*) and a
few others. If the patches are good, should they go to master or to
another branch?
