TYPO3 Core

Since TYPO3 4.5.4, session_start is called very early. This led to Problems with incomplete Objects in the session, like in #29274.

On the frontend, this could be easily circumvented by including or autoloading the classes via preprocessRequest-Hook. On the backend however, there seems to be no hook available, that is called early enough.

Therefore I think it would be useful to have a hook in t3lib_userauth, right before the session is started.

I'll try to submit a patch set on this shortly.
