PHP 7.2.x produces recoverable error when using "user" mode for session management

[kanevbg]

Recoverable Error: session_module_name(): Cannot set 'user' save handler by ini_set() or session_module_name() in app/code/core/Mage/Core/Model/Session/Abstract/Varien.php on line 82

Happens when storing session in DB or in Redis trough Cm_RedisSession

Hey there, thx for submitting.

As you probably know, Magento released PHP 7.2 patches, but I wanted to write THANKS for reporting issues, testing, submitting pull requests. It really really helped since official patch is based on work and input from here ;)

Anyway, this and other issues should be fixed in the official patch.

I won't be merging pull requests at this point, since official patches should be used, hope you're ok with that.
