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

See the thread starting at

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.

 collector 1828 which was already marked as resolved.

(this fixes the infinite loop issue, but adds redundant interface definitions because we can't use Five's bridging code)

- Collector #1815: ZCTextIndex accepts (again) sequences of strings to be indexed.

      - Collector #1812: Fixed key error in ZSQL ZMI/Test

- Forward-port fix from 2.7:

      - WebDAV COPY and MOVE did not call '_notifyOfCopyTo' and
        '_postCopy' hooks like it was done in
        OFS.CopySupport. Additionally added
        'manage_changeOwnershipType' to make MOVE behave even closer
        to OFS.CopySupport.

Shut down cleanly when Windows is shutting down.

The caller can't deal with using current data from loadBefore, so having an "end_tid" of None is useless.

Allow tempstorage to participate in MVCC.  Also fix minor bug where conflict cache could be poisoned by a transaction that failed after store was called.

width 100% did cause an horizontal scrollbar in firefox and ie. This change breaks the ns4 layout a bit, but I guess we can live with that.
