  can discover addresses when dynamic port assignment (bind to port 0)
  is used. This could, for example, be used to update address
  information in a ZooKeeper database.

- Client storagers have a method, new_addr, that can be used to change
  the server address(es). This can be used, for example, to update a
  dynamically determined server address from information in a
  ZooKeeper database.

- Moved some responsibility from runzeo to StorageServer to make it
  easier to use storage servers without runzeo.

A way this to happen is that a transaction is aborted after the
commit process has started. I don't know how this would happen in
the wild.

In 3.10.3, the ZEO tpc_abort call to the server is changed to be
synchronous, which should address this case. Maybe there's another
case.

- 3.10 introduced an optimization to try to address BTree conflict
  errors arrising for basing BTree keys on object ids. The
  optimization caused object ids allocated in aborted transactions to
  be reused. Unfortunately, this optimzation led to some rather
  severe failures in some applications.  The symptom is a conflict
  error in which one of the serials mentioned is zero.  This
  optimization has been removed.

MRUish.

In some experiments, this led to significant reductions in cache miss
rates.
