Fixes https://bugs.launchpad.net/zope.container/+bug/705600.

- checkName now checks the type first in checkName
- Convert most namechooser doctests into unittests
- Added more test cases

Add compatibility with ZODB3 3.10 by importing the IBroken interface from it directly. Once we can rely on the new ZODB3 version exclusively, we can remove the dependency onto the zope.broken distribution.

Copy two trivial classes from zope.cachedescriptors into this package, which allows us to remove that dependency. We didn't actually use any caching properties as the dependency suggested.

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.
