Breaking: #98195 - Remove TODAYS_SPECIAL error constant

See forge#98195

Description

The constant TODAYS_SPECIAL in \TYPO3\CMS\Core\SysLog\Error has never been used in TYPO3 core and is therefore removed without replacement.

Impact

3rd party extensions using the extension will fail with a PHP error.

Affected installations

3rd party extensions who use the TODAYS_SPECIAL constant.

Migration

3rd party extensions using the TODAYS_SPECIAL constant should replace all usages with the integer value 100 or use a custom class with a user defined constant.
