TYPO3 Core

The new TYPO3 8 core Linkhandler functionality works just fine, but a hook would be useful to allow extension developers to handle some parameters before the typolink be generated. This functionality was provided by some of the old Linkhandler extensions and for those who used it on previously versions, the absence of the hook could lead to configuration problems.

I attached a patch file that modifies \TYPO3\CMS\Frontend\Typolink\DatabaseRecordLinkBuilder->build to create the hook. Please tell me what you think about it.
