  o Major bugfixes (relay, OOM handler):
    - Fix a timing-dependent assertion failure that could occur when we
      tried to flush from a circuit after having freed its cells because
      of an out-of-memory condition. Fixes bug 20203; bugfix on
      0.2.8.1-alpha. Thanks to "cypherpunks" for help diagnosing this
      one.

When clearing cells from a circuit for OOM reasons, tell cmux we did so. Not telling the cmux would sometimes cause an assertion failure in relay.c when we tried to get an active circuit and found an "active" circuit with no cells. Additionally, replace that assert with a test and a log message. Fix for bug 20203. This is actually probably a bugfix on 0.2.8.1-alpha, specifically my code in 8b4e5b7ee902fb7fa0776 where I made circuit_mark_for_close_() do less in order to simplify our call graph.
