mod_s2s: Don't call ondisconnect manually, don't call conn:close() 3 times (!) and merge its logic and streamdisconnected into session_close - including now waiting for a reply </stream:stream> if there is the chance of further stanzas requiring delivery arriving. session.sends2s() on a half-closed stream returns false.
