revert revision 72313:

  "add new 64-bit btree types (patch from Jim), merged from trunk"

Even though, as noted in the history file, there is no official release
of standalone ZODB 3.7, it corresponds with the release of Zope 3.3 and
2.10 in 2006, and should be considered feature-frozen.  Jim has
requested that these changes be reserved for the trunk (to be ZODB 3.8).

A subsequent checkin will clarify the status of 3.7 in HISTORY.txt.

 ------
 
-- Added support for 64-bit integer BTrees as separate types.  
-
-  (For now, we're retaining compile-time support for making the
-   regular integer BTrees 64-bit.)
-
 - Support for 64-bit integer keys and values has been provided as a
   compile-time option.
