Fully deprecate both CatalogAwareness and CatalogPathAwareness. They are untested and unused. Event subscribers for zope.lifecycleevents are the way to go.

Emit a deprecation warning for ``Products.ZCatalog.CatalogAwareness``. The module was already deprecated according to its docstring. Since some five:deprecatedManageAddDelete directive in OFS always imports the module, we only emit the warning on actual use of the CatalogAware class.

Removed deprecated ``catalog-getObject-raises`` zope.conf option. The option was slated for removal in Zope 2.10.

Remove inline tutorial, this is better covered in http://docs.zope.org/zope2/zope2book/SearchingZCatalog.html

Avoid bare except's and catch Exception instead - this won't catch system exceptions like KeyboardInterrupt, MemoryError and similar things

Removed unmaintained HelpSys documents from ZCatalog and PluginIndexes. Useful explanations are given inside the form templates.

- no need to re-raise Redirect in raise_standardErrorMessage (ZPublisherExceptionHook is responsible for that)

More catalog work, merge in the non-queryplan and non-btree changes of queryplan and optimize more of date range index internals
