 commit 94bfbf7859
 Author: Nick Mathewson <nickm at torproject.org>
 Date:   Tue Jul 23 10:41:57 2019 -0400

     Use special magic to enforce manager/object connection.

     Every time we finalize a config manager, we now generate a new magic
     number for it, so that we'll get an assertion failure if we ever two
     to use an object with a different configuration manager than the one
     that generated it.
 }}}

 I have tried to guess the commits that fix these issues, but I'd like you
 to confirm on the PR:

 Please add runtime magic generation uniqueness tests:
 https://github.com/nmathewson/tor/pull/3#discussion_r317550341

 Please add subconfig tests:
 https://github.com/nmathewson/tor/pull/3#discussion_r317552964

 Do we need unit tests that have non-managed fields?
 https://github.com/nmathewson/tor/pull/3#discussion_r317553659

 There aren't any tests that use a clear callback. Please add some.

 This CI build hung:

 https://ci.appveyor.com/project/nmathewson/tor/builds/26996434
 Let's check both torproject and nmathewson CI again after the fixes listed
 above.
