- There's a new utility script, strip_versions that strips version
  data from storages. This is needed to prepare databases containing
  version records for using ZODB 3.9, which no-longer supports
  versions.

- Fixed vulnerabilities in the ZEO network protocol that allow:

CVE-2009-0668 Arbitrary Python code execution in ZODB ZEO storage servers
  CVE-2009-0669 Authentication bypass in ZODB ZEO storage servers

- Limit the number of object ids that can be allocated at once to
  avoid running out of memory.

for large databases on systems that don't allow many subdirectories.

distutils-compatible method but it failed miserably.

These files were missing:

  BTrees/Development.txt
  ZEO/scripts/README.txt
  ZODB/scripts/README.txt
  ZODB/scripts/referrers.txt

 - moved setuptools import in setup.py before distutils import to allow
   setuptools to apply its patches

add missing file and fix setup.py so the error would have been caught when I ran the tests before the previous checkin

(For now, we're retaining compile-time support for making the
   regular integer BTrees 64-bit.)

(Merged from 3.7 branch.)
