Merged branches/tiran-zpt-pydefer r29702:30399 into trunk (including manual merge because I renamed the original branch)

- A quote too much

After consulting with Mark Hammond, removed the explicit calls to SvcStop().

That method gets invoked automatically by the services framework when a
stop request is generated.  Calling it explicitly too caused the onStop()
method to get called multiple times.  At least ZRS's Service subclasses
have onStop() methods that can't be called multiple times without raising
exceptions (they shut things down, and stuff like sockets go away the
first time onStop() gets called).

* Implement a file handler with 'rotate'.  This closes the file, attempts
  a rename to {filename}.last, then reopens the original name.  This
  then makes the log available for another process to perform the rotation
  logic on. This log handler is only installed on the Windows
  platform, where you can't rename an open file.

|- Add version_txt target
|- Call version_txt target from install target
|

Major service enhancements.  Service cleanly shuts down child, and if child
fails the tail of the process output (which generally contains a traceback)
is
written to the event log.

Minor tweaks to the Windows build 'clean' process and documentation tweaks.

Don't kill the service if we can't write to the event log

* Register the new signal handlers on Windows

* Implement a signal mechanism for Windows utilising Windows 'Named Events'.
  See comments in WinSignalHandler.py for details.
* As Windows can not rename an open file, when the 'reopen' signal is
  received try and call a 'rotate' method rather than a reopen.  Rotation
  itself is implemented in zLOG.LogHandler

containers. This is necessary to satisfy expectations of python-script
security machinery.

Added a special case for old ZClass records.

Keep defer expression like it was coded by Evan. Added new expression type lazy: that works as a lazy initialization expression. Also added some doc strings

at the end even if there were test failures and/or errors, and
didn't display any failure/error tracebacks at the end.  Now it
reports failures/errors at the end the same as when -p isn't
passed.

Two of the ZClasses tests are disabled here, because they
run afoul of Zope trunk's security machinery.  Jim needs to look
at them.  A blurb also needs to be added to CHANGES.txt.

Here are checkin msgs from the branch relating to Zope code
(the msgs relating to ZODB code were reproduced in the
ZODB 3.4 branch checkin):

    Fixed some code for registering class changes to avoid the

tuple if the class has a non-empty module string.

There's really no point, because created objects will be unreachable
after invalidating old objects.  Also, if a created object is
non-ghostifiable, it will try to load it's state again, and then
either it would fail or it would load non-committed state.

Use explicit tm for second connection rather than separate thread.

Added copy test
