Collector 789:  Zope's transaction behavior flawed.
                                                                                
Historically, errors that made it up to the publisher have run outside the
context of a transaction.  This has caused problems for applications which
expect to be able to write to the database (if only temporarily, before
transaction.abort() is eventually called).
                                                                                
With this patch, we allow the error to execute in the same transaction as
the "main" request, and abort only after the error has executed.

Ensure that persistence machinery is tickled when __setitem__, __delitem__,
clear, and update are called on a transient object.

Also, use a distinct logger for error logging.

- Add "instance-local" "period" to TransientObjectContainer.  This allows
  users to dial a knob which may (or may not) reduce the number of conflicts
  that happen during heavy sessioning usage by reducing the frequency at
  which buckets potentially expire at the cost of expiration time
  accuracy.  Previously, this setting was hardcoded to 20 (seconds) at
  module scope.

- Add 'session-resolution-seconds' to zope.conf.in/zopeschema.xml to
  control instance-local period for /temp_folder/session_data.

- Update TOC UI, interface, and help files to deal with instance-local
  period.

- Update OFS/Application to deal with instance-local period for default
  /temp/session_data TOC.

- Use __setstate__ for TOC upgrade instead of a dedicated _upgrade method
  (it was too hard to figure out where to call _upgrade from and when to
  call it).

- Perform a few formatting changes that should make it easier to merge the 2.7
  branch with the HEAD going forward.  I beseech those who make formatting
  changes to a branch or the HEAD make them to the other at that time
  as well, especially with the SVN/CVS split it's very painful to do merging
  when there are non-substantive differences between HEAD/maint.  When I was
  a child, I never thought I would need to use the word "beseech", however, it
  has indeed happened.

     - Collector #1345: AcceleratedHTTPCacheManager now sends the
       Last-Modified header.

- Simple parameterization of BUCKET_CLASS for testing/debugging purposes.
  BUCKET_CLASS can be set to something like "dict" in order to isolate
  future problems potentially caused by OOBTrees (not that there seem
  to be any, but it's nice to be able to confirm).
                                                                                
- Log at INFO level in TLOG instead of BLATHER.
                                                                                
- Fix "off by one" error in _getCurrentSlices and explain.
                                                                                
- Add various DEBUG and TLOG statements for testing/debugging purposes.
                                                                                
- Arrange to compare against "default" instead of "_marker" in .get.
                                                                                
- Use random.uniform instead of random.choice to decide how to sleep.
                                                                                
- Use "_wrap" instead of directly calling __of__ for consistency.

Do logging only if Z_TOC_DEBUG environment variable is set.

Raise ConflictError from _p_resolveConflict instead of returning None if
conflict cannot be resolved.  I think someone changed the contract of
this method but the code hasn't caught up til now.

Port mergeResults() tests

       splitlines() instead of split('\n').

docstring instead, as the new style suggests.

  - replaced old CVS expansion with a clean $Id$
  - set the svn:keywords property to "Id"

When you check-in files in the future and want $Id$ to be expanded,
make sure it reads "$Id$" in that file; then set svn:keywords to "Id".

ZODB, ZEO, Persistence and similar packages were not modified since they
are really maintained elsewhere. Right now, we use a copy of them in our
Zope/Zope3 trees. We should go back to the module sharing (using
svn:externals).
