Log Message:
Running AdaptableStorage with the latest Zope revealed some flaws.
Fixed them all.

- Consistent ordering of transaction participants now makes it impossible to
  add a jar to the transaction after the commit() method has begun.
  AdaptableStorage (and perhaps other projects like ZPatterns) relied on
  the ability to add a jar after commit has started.  This could lead to
  a deadlock.  Reworked ASStorage, FSConnection, and the tests to deal with

- Serials are now required to be hashable.  This makes serials, used to
  prevent conflicts, simpler and more robust.

- DBTab needs some kind of class it can call directly, so I added
  the small subclasses FSStorage and FSDatabase to Zope2FS.

- Restored the PersistentExtra patch.

- The directory items gateway wants to write data about its children, but
  sometimes its children aren't being written at the same time.  Added
  a "conditional" optional flag to FSConnection.writeSection(), allowing
  data to be written only if other data gets written.
