[SM-PLUGINS] Avelsieve and Cyrus Imap on CentOS 7

[<mi...@je...>]

I'm trying to use plugin Avelsieve on CentOS 7 with the timsieved server
from Cyrus Imap.

I've solved a few setup issues and was hoping for success, however, now I
face the following fatal php error:

PHP Fatal error:  Call to undefined function session_unregister()

According to php documentation:

http://php.net/manual/en/function.session-unregister.php

these calls are now removed.

According to my log there are a few function calls that may be removed in
future versions:

Removed (unknown) calls: unregister() (and probably register())
Deprecated calls: ereg() and split()

I finally gave up and reverted to smartsieve,
http://smartsieve.sourceforge.net/ , which is now functional. However, I
would prefer to use a system integrated with squirrelmail. (Smartsieve also
reveals its age in the log).

Kind regards,
Michael
