Breaking: #82640 - Re-arranging global debug functions

See forge#82640


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.


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.


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.
