[vala] vapi: "ref" functions must return an unowned value



commit 73105043ef3b12cdac538d4a9b8059ad7e02f8d5
Author: Rico Tzschichholz <ricotz ubuntu com>
Date:   Tue Jan 17 12:52:47 2017 +0100

    vapi: "ref" functions must return an unowned value
    
    Otherwise vala would automatically add a corresponding "unref" call.
