Make the tests a bit faster, there's really no difference between 100 and 1000 catalog entries. Testing really large numbers would be a different and interesting story.

Removed catalog length migration code. Direct upgrades from Zope 2.7 and earlier are no longer supported.

Don't produce warnings in our tests, only catch warnings for the one method that actually is supposed to emit it

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
