Deprecation: #54152 - Deprecate arguments of BackendUtility::getPagesTSconfig 

Description 

BackendUtility::getPagesTSconfig($id, $rootLine = null, $returnPartArray = false) allowed the following arguments:

• $id: This argument was and still is required. It's the id of the page the TSconfig is fetched for
• $rootLine: This argument was optional and allowed to use that method with a custom rootline. That argument is deprecated now.
• $returnPartArray: This argument was optional and allowed to return the TSconfig non parsed. That argument is deprecated now.

Impact 

Calling BackendUtility::getPagesTSconfig with $rootline and/or $returnPartArray being different than their default value, will write a deprecation log entry and will stop working in TYPO3 v10.

Affected Installations 

All installations that call BackendUtility::getPagesTSconfig with $rootline and/or $returnPartArray being different than their default value.

Migration 

Calling BackendUtility::getPagesTSconfig with just the id argument still behaves the way it does. It's the most common use case and there's no migraton needed.

If you called BackendUtility::getPagesTSconfig with $returnPartArray being true in the past, you should now call BackendUtility::getRawPagesTSconfig. You will get the non parsed TSconfig, just like before.

If you called BackendUtility::getPagesTSconfig providing a custom rootline via $rootline in the past, you should now call BackendUtility::getRawPagesTSconfig($id, $rootLine = null) with your custom rootline and parse the returned TSconfig yourself, just like BackendUtility::getPagesTSconfig does.
