Breaking: #97452 - Removed EditFileController hooks 

See forge#97452

Description 

The hooks $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/file_edit.php']['preOutputProcessingHook'] and $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/file_edit.php']['postOutputProcessingHook'] have been removed, since adjusting the generated content can be achieved using template overrides and modifing the form data, used to generate the edit file form, can be done using the PSR-14 \TYPO3\CMS\Filelist\Event\ModifyEditFileFormDataEvent .

Impact 

Any hook implementation registered is not executed anymore in TYPO3 v12.0+. The extension scanner will report possible usages.

Affected Installations 

All TYPO3 installations using these hook in custom extension code. This is pretty unlikely, since both hooks were of limited use.

Migration 

The form data modification, allowed by preOutputProcessingHook, can be achieved with the new PSR-14 ModifyEditFileFormDataEvent.

The content manipulation postOutputProcessingHook hook can be substituted with a template override as outlined in this changelog entry.
