Deprecation: #80510 - ContentObjectRenderer->URLqMark 

See forge#80510

Description 

The PHP method ContentObjectRenderer->URLqMark() has been marked as deprecated. It was used to add a ? between two strings if the first one does contain a ? already.

Its main purpose is to add query string parameters to a given URL.

Impact 

Calling the method above will trigger a deprecation warning.

Affected Installations 

Any installation using custom extensions calling this method.

Migration 

Implement this functionality with PHP's native (strpos($haystack, '?') !== false ? '?' : '') one-liner directly.
