commit eccbd97e1f2599bfb76818fe6bc32967ed07e0c7
Author: Alexander Barton 
Date:   Wed Sep 25 01:29:23 2013 +0200

    Remove CLIENT.oper_by_my, Client_SetOperByMe() and Client_OperByMe()

    All places where Client_OperByMe() is used can either be converted to
    Client_HasMode(Client, 'o') or Op_Check().

    And Op_Check() itself can use the connection handle for deciding whether
    the IRC Operator is a local user or not.
