QUIC: limited the number of client-initiated streams. The limits on active bidi and uni client streams are maintained at their initial values initial_max_streams_bidi and initial_max_streams_uni by sending a MAX_STREAMS frame upon each client stream closure. Also, the following is changed for data arriving to non-existing streams: - if a stream was already closed, such data is ignored - when creating a new stream, all streams of the same type with lower ids are created too
