Breaking: #75323 - Removed parameter entryPointPath from main applications

See Issue #75323

Description

The entry point PHP classes for index.php, typo3/index.php and so forth (called "Application classes") now have a parameter not to define the path to the entry point but the number of subdirectories under the main installation path, allowing to not specify the name of the path, but just the levels of subdirectories.

Subsequently, the methods Bootstrap->baseSetup(), Bootstrap->redirectToInstallTool() and SystemEnvironmentBuilder::run() now expect an integer as parameter, instead of the path to the entry point script.

Impact

Calling one of the methods above with a string as parameter instead of an integer will fail because the calculation for PATH_site which is the base for the whole installation will fail.

Affected Installations

Any installation with custom entry points or custom extensions with separate entry points.

Migration

Use the entry point level as integer, instead of the string, in your custom entry points. See TYPO3\CMS\Backend\Http\Application for an example.
