Remove deprecated zope code from the canonical package

[Curtis Hovey]

The canonical package is filtering all deprecation warnings because there are many modules that call methods or ZCML directives that are deprecated in Zope 3.4. For example:

ZCML
    directive <content> => <class>
    directive <vocabulary> => <utility> with the provides set to IVocabulary

Packages
    zope.app.mail => zope.sendmail
    zope.app.session => zope.session
    zope.app.error => zope.error
    zope.app.datetimeutils => zope.datetime
    zope.app.publisher => zope.publisher
    zope.app.security => zope.security

Classes
    zope.app.component.fields.LayerField => zope.configuration.fields.GlobalInterface
    zope.app.event.objectevent.ObjectEvent => zope.component.interfaces.ObjectEvent
    zope.app.event.objectevent.ObjectCreateEvent => zope.lifecycleevent.ObjectCreateEvent
