topic: disallow use of topics without obsolete enabled

This is a prelude to allowing changing topics. The experience will be
disastrous without obsolete markers, so let's just preempt any
potential problems.

# topics

Topics are an experiment to see if maybe the workflow defined by git
branches and hg bookmarks is only partially what users want - perhaps
something that feels more like a traditional VCS branch is right, but
that it should "dissolve" upon being finished. This extension exists
to be a sandbox for that experimentation.

# usage

Enable topics like any mercurial extension: download the source code to a
local directory, and add that directory to your `.hgrc`:

    [extensions]
    topics=path/to/hg-topics/src
