We do not need explicit IPROTO_STREAM_NEW/DELETE. A stream is
created on a first message with the new STREAM_ID, and can be
deleted either right after last pending request is processed, or
after some timeout - it does not matter. The only purpose of streams
is to hold on pending messages with equal stream ids until currently
executing one is not processed.
