This fixes compatibility problems with zope.testing 3.8.4.

Move IXMLRPCPublisher ZCML registrations for containers from zope.app.publisher to zope.container for now.

  to ``zope.location.interfaces``.  A b/w compat import still exists
  to keep old code running.  Depend on ``zope.location``>=3.5.4.

- Rid ourselves of ``IObjectMovedEvent``, ``IObjectAddedEvent``,
  ``IObjectRemovedEvent`` interfaces and ``ObjectMovedEvent``,
  ``ObjectAddedEvent`` and ``ObjectRemovedEvent`` classes.  All of
  these were moved to ``zope.lifecycleevent``. Depend on
  ``zope.lifecycleevent``>=3.5.2.

  condition on the qsubscriber ZCML directive that registers the
  CheckDependency handler for IObjectRemovedEvent.  If
  ``zope.app.dependable`` is not installed, this subscriber will never
  be registered.  ``zope.app.dependable`` is now a testing dependency
  only.

  zope.traversing.api.getPath in favor of using
  ILocationInfo(object).getPath().  The rest of the runtime
  dependencies on zope.traversing are currently interface
  dependencies.

- added coverage analysis

(Thanks to Gary Poster for the idea, see r98787)

  ``IOrdered`` interface and let ``IOrderedContainer`` inherit it. This allows
  easier reuse of the declaration.

As 'setuptools' is a dependency 'pkg_resources' will be available always. Ref: http://mail.zope.org/pipermail/zope-dev/2009-March/035277.html

  o ``zope.exceptions.DuplicationError`` -> ``KeyError``

  o ``zope.exceptions.UserError`` -> ``ValueError``
