Revert session_serializer_name(), session_gc()

Hello, I just saw this in the 5.6-alpha1 changelog: - Implemented Request #54649 (Create session_serializer_name()). (Yasuo) ... - Implemented Request #11100 (session_gc() function). (Yasuo) I didn't find an RFC and I don't know a way to search for a discussion on internals (Google doesn't find one). session_serializer_name(): https://bugs.php.net/bug.php?id=54649 I don't think that this should've been implemented, especially with the reasoning from the feature request ... The same could be applied to all session ini options and especially now since session_start() accepts them, it's useless IMO. session_gc() was added in a similar fashion: https://bugs.php.net/bug.php?id=11100 There's already a comment about how the same thing can be achieved by overloading SessionHandler::gc(), but a user could also just alter session.gc_divisor, session.gc_probability to ensure that the garbage collector is started. And while session_serializer_name() is just redundant, session_gc() could cause performance issues. I'd strongly suggest that these 2 functions should be removed before PHP 5.6 is officially released. Regards, Andrey Andreev.
