Log Message:
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.

+Pickle (in-memory Connection) Cache
+-----------------------------------
+
+You probably never saw this exception:
+
+    ``ValueError: Can not re-register object under a different oid``
+
+It's been changed to say what it meant:
+
+    ``ValueError: A different object already has the same oid``
+
+This happens if an attempt is made to add distinct objects to the cache
+that have the same oid (object identifier).  ZODB should never do this,
+but it's possible for application code to force such an attempt.

 Release
