RFC Messageflow for ADD_INCOMING_STREAMS mustbe add with RECONFIG_RESPONSE

[hoelscher]

The messageflow in RFC 6525 for Add Incoming Streams Requests is worng. In the messageflow showed in RFC 6525 there is a Reconfig Response missing which send the receiver of Add Incoming Streams Request. If it is missing, there is now way to stop the reconfig timer which is running for the Add Incoming Streams request. So the best way is to combine the Add Outgoing Stream Request with a Reconfig Response parameter in one Reconfig Chunk. So this combination must be add to the allowed combinations in the RFC.
E-A E-Z
----------------[RE-CONFIG(ADD_IN_STRMS:X/3)]----------------->
<----[RE-CONFIG(ADD_OUT_STRMS-REQ:Y/3,RESP:X)]------
---------------------------[RE-CONFIG(RESP:Y)]----------------------->
Else there is no information to stop reconfig timer. Therefore the combination of ADD_OUTGOING_STREAMS and RESPONSE must be put in list of allowed combinations of parameter.
