commit 5e01b61bf89316086fe569f6eb0254c67c9c3349

    Initialize the supplementary group access list for all daemons
    
    Ensure __pmSetProcessIdentity correctly initializes supplementary
    group access list, so that we don't end up with whatever was set
    there by the caller (which can include group 0 and other system
    groups).
    
    Update pmproxy to call __pmSetProcessIdentity instead of the open
    coded implementation it had previously (from the days when it ran
    as user "nobody").
