Breaking: #88427 - jsfunc.evalfield.js has been removed 

See forge#88427

Description 

The file jsfunc.evalfield.js, responsible for form value evaluation and validation, has been removed. This job is now done by TYPO3/CMS/Backend/FormEngineValidation since TYPO3 7.4.

Impact 

Extensions still relying on this file and its API will not work anymore.

Affected Installations 

All installations with third party extensions using this API are affected.

Migration 

In most cases no migration is necessary, unless this API is used in a custom built form. In such case, migrate to FormEngine API to automatically use the new API.
