[tor-commits] [tor/master] Add a quick-and-dirty-test for generate_v2_networkstatus.

commit 0f83fcc5c239776211d0c111c628a7f95a802808
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date:   Tue Apr 2 12:45:12 2013 -0400

    Add a quick-and-dirty-test for generate_v2_networkstatus.
    
    It sure is a good thing we can run each test in its own process, or
    else the amount of setup I needed to do to make this thing work
    would have broken all the other tests.
    
    Test mocking would have made this easier to write too.
