The ZODB4 BTrees excludemin/excludemax arguments got implemented

 - 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.

positive_id():  Use a trick from Armin Rigo to deduce the
native platorm address size.

Port from ZODB 3.2.

Change FileStorage .restore() and .store() to update max oid in use.

This is the last of the checkins to fix critical bugs involving rare cases
where a FileStorage could end up reusing old oids for new objects.

Port from ZODB 3.2.

Stop believing the maximum oid cached in a FileStorage's .index file.

This is a critical bugfix, although the problems it addresses are
(a) rare; and, (b) not entirely fixed yet (more checkins to come).

The true max oid is found efficiently now by exploiting the recently-added
fsIndex.maxKey() method (which was, of course, added for this purpose).

Also fix that the .index file could get updated on disk when the
FileStorage was opened in read-only mode.  The code was trying to prevent
this, but missed the most obvious rewrite path.

Incidentally improved many obsolete and/or incorrect comments.

Give fsIndex an efficient maxKey() implementation.

This will (in a later checkin) be used to give FileStorage an "obviously
correct" way to determine the largest oid used in an .fs.index file.

Note that cPickleCache.c must be recompiled else the new test will fail.

Change the exception raised when an attempt is made to add two objects to
the cache with the same oid.  The former messsage didn't make sense.

Add a test to verify that this exception does get raised, and that the
message given is the intended one.

This is the first of a series of checkins, to fix critical bugs where
ZODB can in fact raise this exception in rare, but normal, use cases.

setUp():  Use a much smaller (than default) ZEO client cache.

The current default is 200MB, and at least testSerialization reads
the entire cache file into one giant string.  That grossly boosts
the process highwater mark when running the tests.  Windows reclaims
the memory after, but other platforms may not.

Cool:  testSerialization was one of the slowest tests before, but
is 100x faster now.
