Breaking: #96829 - Removed BackendUtility->getFuncInput()

See forge#96829

Description

Method BackendUtility::getFuncInput() is incompatible with Content-Security-Policy HTTP headers due to its onchange JavaScript handler, and has been removed.

Impact

Instances with extensions using the method will raise a fatal PHP error upon use.

Affected Installations

The method is part of very old-school backend module code and of limited use. TYPO3 core code does not use it since at least v9, it is relatively unlikely backend modules of extensions still use this method. The extension scanner finds usages with a strong match.

Migration

No direct migration available. The input field HTML should most likely be inlined to a template and eventual JavaScript events should be handled with a JavaScript module.
