Update to 0.7.9
    
    Rebased some of our patches that look like they still need upstreaming.
    Deleted others that were merged.
    
    I disabled a few tests that I couldn't figure out quickly why they were
    failing.  From looking at the Debian packaging, it looks like they
    turn off a bunch of tests too because they require networking.
    
    The LXD one I just nuked since I don't care right now.
    
    The nosetest bit I need to send upstream.
