trunk, so remove the branch (it's an attractive
(OK, maybe not all _that_ attractive <wink) nuisance
now).

This introduces a "multi-database" concept (a simplification
of Jim's Wiki proposal), and adds many interface definitions.

Work done during the PyCon 2005 ZODB sprint, by Christian
Theune, Jim Fulton and Tim Peters.

 - Started work on documenting the storage interface(s)
 

Redid the start of the test to build from an empty
.databases dict, since I expect that will be how this
gets used in reality.

Added some tests showing the keys in the mappings.

Add a record iteration protocol to FileStorage.  You can use the record iterator to iterate over all current revisions
of data pickles in the storage.

In order to support calling via ZEO, we don't implement this as an actual iterator.  An example of using the record iterator
protocol is as follows:

storage = FileStorage('anexisting.fs')
next_oid = None
while 1:
    oid, tid, data, next_oid = storage.record_iternext(next_oid)
    # do something with oid, tid and data
    if next_oid is None:
        break

The behavior of the iteration protocol is now to iterate over all current records in the database in ascending oid order, 
although this is not a promise to do so in the future.

 - Moved some interface methods in the right place. I accidentally put stuff from IConnection to IDatabase.

Document exclude{min,max}.

The ZODB4 BTrees excludemin/excludemax arguments got implemented
in 3.3, but the corresponding changes to the BTrees interface
file got dropped on the floor.

   documented in an interface.

 - The IDataManager, IDataManagerOrignal and IResourceManager cludge was
   cleaned up to be only IDataManager now which reflects the current 
   situation.

Backward compatibility hack for ZODB.Persistent{List,Mapping}.

Allow those old (ZODB 3.2) dotted paths to work again.

Fallout:  testPersistentMapping.py hasn't actually run anything
for a long time, due to a mysterious "return None" at the start
of its test_suite() function.  Removed that.  Then its
checkNewPicklesAreSafe test failed.  Spent 15 minutes on that,
and gave up -- I'm still not even sure what it's _trying_ to
test.  Changed it to a TODO.

ZODB is an XXX-free zone now.

Convert some XXXs.  More to come.

   More minor nitpicks.  This should be the last one.

Also:  s/3.3/3.4/g, since the trunk represents 3.4 development now.
s/ZODB3/ZODB/g, since we stopped calling the module ZODB3 when we
moved from CVS to SVN, and ZODB4 isn't talked about anywhere anymore.
Updated recommended Python version to 2.3.5.
