      Change test.py to use zope.testing.testrunner, and update the
      latter to Jim's development version.  Hardest part turned out
      to be teaching ZODB's setup.py how to "build" this version of
      zope.testing (it has a lot of packages in a test directory,
      where the latter is not itself a package).
      
      Incidentally repaired an oversight in building zope.interface
      too.

      checkUndoInVersion():  Add an optional `hook` argument.
      
      This gets called "in the middle" of the test, if specified.
      ZRS 1.5 uses this to pass a callback that arranges to start a
      ZRS secondary then.  ZRS had its own copy of this test, but
      it's a miserable & messy test, and the copy it had failed in
      5 different places when using ZODB 3.4 (it had gotten way of
      synch with changes since ZODB 3.2).
      
      Also removed all traces of the bizarre _x_dostore() method.
      Not sure what that was about, but if the comments were right
      we don't care about ZEO 1.0 anymore.

      Jeez Louise, the new tests I added for undoInfo+undoLog work fine

      without a primary to recover from.

      Fix obscure bug.
      
      If a threaded transaction manager ever passed None to
      the Transaction constructor's `synchronizers` argument, then
      synchronizers registered later in the same transaction
      were invisible to the transaction, and so their afterCompletion()
      methods wouldn't get called when the transaction ended.

      ISynchronizer grows a newTransaction() method, called
      whenever TransactionManager.begin() is called.
      
      Connection implements that, and changes its ISynchronizer
      afterCompletion() method, to call sync() on its storage
      (if the storage has such a method), and to process
      invalidations in any case.
      
      The bottom line is that storage sync() will get done "by
      magic" now after top-level commit() and abort(), and after
      explicit TransactionManager.begin().  This should make it
      possible to deprecate Connection.sync(), although I'm not
      doing that yet.  Made a small but meaningful start by
      purging many sync() calls from some of the nastiest ZEO
      tests -- and they still work fine.

      Port from ZODB 3.2.
      
      Added new test checkSubtxnCommitDoesntGetInvalidations to
      verify that a longstanding bug in subtransaction commit is
      repaired.
      
      Jim (Fulton) discovered this in ZODB 3.4's code, while implementing
      savepoint/rollback.  Same bugs had been there at least since ZODB 3.1.
      
      Also added news about the bug.

      Changed the strategy for managing savepoints.  The requirements
      for savepoint management are:
      
      - All savepoints for a transaction should be invalidated when the
        transaction commits or aborts
      
      - If a savepoint is rolled back, then all savepoints after it within
        a transaction must be invalidated.
      
      We previously implemented these requirements by organizing transaction
      savepoints into a doubly linked list.  This was overkill.  We didn't
      have need for such fine-grained ordering.  This strategy had the
      disadvantage that it kept all savepoints around until the transaction
      ended.  Savepoints could be expensive to keep and it's possible that
      some applications could keep a lot of them.
      
      The new stragey is to:
      
      - Keep weak references to savepoints.  We can forget about savepoints
        that the application isn't using.  Any resources used by these
        savepoints can be freed.
      
      (We have to keep a strong reference to the last savepoint used for
        a subtransaction.)
      
      - We assign indexes to savepoints within a transaction.  When a
        savepoint is rolled back, in addition to invalidating that
        savepoint, we also invalidate savepoints with a higher index.
      
      A side effect of this change is that code using the savepoint API
      should interfere less with code using subtransactions.  Of course, we
      really need to phase out code that uses subtransactions.
      
      It is likely that we can leverage this change in strategy to speed
      creation of ZODB connection savepoints.  Creating a ZODB connection
      savepoint now requires copying the savepoint storage index.  This
      index could become large.  If applications aren't holding on to old
      savepoints, then it is possible that we could avoid this copy.

      An internal 3.4a5 release, to incorporate savepoint fixes.

      Fixed a bug in savepoint rollback.  It's not enough to rollback
      just the savepoint being rolled back because later savepoints
      might involved data managers that hadn't joined when the savepoint
      being rolled back was created.
      
      Now, when a data manager joins and we have savepoints, we create a
      data manager savepoint for the new data manager and add the
      datamanager savepoint to all previous transaction savepoints.  Note
      that this data manager savepoint can be a special savepoint that just
      calls abort on the data manager when it is rolled back.
