Breaking: #82640 - Re-arranging global debug functions

See Issue #82640

Description

The global function xdebug() has been dropped in favor of using debug() .

The global function debug() now only takes a maximum of three function arguments.

Impact

Calling xdebug() globally will throw in a PHP fatal error.

Affected Installations

Any TYPO3 installation in a development environment using the global functions in an old-fashioned way.

Migration

Instead of xdebug() simply use debug() as an alias. Ensure that when calling debug() that a maximum of three arguments are handed over to the function.
