Breaking: #85036 - Removed support for non-namespaced classes in Extbase

See forge#85036

Description

Non-namespaced classes like Tx_Extension_Controller_FooController are not supported any more and all magic based on class names no longer works with classes like these:

  • Translating model name to repository name (and vice versa)
  • Translating model name to validator name
  • Guessing the extension name
  • Guessing the controller name by looking at a command name
  • Translating model name to (database) table name
  • Recognizing child property types in object storage annotations

Impact

All this magic no longer works with non-namespaced classes.

Affected Installations

All installations that still use non-namespaced classes in Extbase.

Migration

Use namespaced class names for Extbase.
