Bug#729956: Forwarded upstream

[Diane Trout]

Hi

I pushed my work to alioth on the branch detrout-python3

I modified the statsmodels build recipe to at least partially use
pybuild, and the documentation build uses python 3 components instead
of python 2.

I skipped the 4 tests that failed for me, that had an upstream bug
report, when a new version comes out those skips need to be removed.

I tried rebasing on Yuri's latest commit but there was conflicts over
which version of ipython to use that I'm to tired to resolve right now.

It builds python 2 and python 3 statsmodels and statsmodels-lib as well
as the documentation. (including the example notebooks)

There was also some changes because there's were new temp files that
dh_auto_clean needed to fix.

I tried to commit changes in logical chunks for easier review.

There's still problems with dependencies in sid, so all my testing was
against my unclean testing laptop.

Someone should probably debdiff the package against a previous build to
see if anything important got lost.

If it looks good we can discuss if I need to rebase, or if you just
want to merge this work, but right now I need to go to sleep.
