ZCatalog instances

o The value  is written to standard error when the request completes (forward
  ported from 2.7 branch).

Patch from Dieter Maurer, with tests sponsored by a bounty from Logicalware.

This change reverts 'guarded_getitem' to pass the 'index' argument as
the name to 'validate'.  This change will *not* be propagated to the
trunk, because the resolution of #1182 specifies that the reverted
behavior (i.e., passing None for item accces) is to become the standard
implementation as of 2.9.

from UnIndex)

If the new value is _marker (basically, if we index with a value of
None), we should also remove the object from our _unindex

  - deleted trailing whitespace

  - new test for removal (indexing an object with a value of None
    should remove it from the index)

and not just when the file is missing. This is a forward port from Zope-2_7-branch.

      - Collector #1871: Applied patch to support lists with records using 
        ZTUtils.make_query()

        work properly with a top-level user folder with enabled password
        encryption.

(there's no possiblity of rollback here, so no need to insist that the
data manager support rollbacks).

The other part of this change is in ZODB 3.4.1b4, also stitched in
by this checkin.

- added z3 -> z2 interface bridge

Avoids exiting the zopectl shell, if run from there.

- made sure custom strings like MessageID are not converted by ustr
- synced TALInterpreter code and tests with zope.tal where possible without changing behavior
- backported MessageID support from zope.tal

for gory details.

Note that Zope trunk and 2.8 also have a third copy of this
code, in

    lib/python/zope/server/trigger.py

That's "a Zope3 problem".

      - Collector #1807: fixed memory leak in cAccessControl.guarded_getattr()

Additional test. CMF requires this behaviour.

Display offending line when warning about getOwner(1) deprecation.

Will stitch in again via svn:externals.

(http://www.zope.org/Collectors/Zope/1813).

o CMFCore will include it after 1.5, with an appropriate module alias for
  backward compatibility.

This also includes a patch to HTTPRequest which is implemented
directly in Zope 2 rather than the monkey Five does.

- ported and reversed bridging code from Five
