Deprecation: #66905 - Deprecate uc->classicPageEditMode and editRegularContentFromId option 

See forge#66905

Description 

The BE-User uc option "classicPageEditMode" which was used prior to TYPO3 CMS 4.0 has been removed some time ago. The functionality editRegularContentFromId which was then triggered in EditDocumentController has been marked for deprecation.

Impact 

Any direct calls using editRegularContentFromId via GET parameter or calling editRegularContentFromId() directly from a third-party extension will trigger a deprecation message.

Affected Installations 

Any installation using third-party code to restore the old behaviour.

Migration 

Remove calls to the functionality.
