Adjust the mechanism for MAX_STREAMS_BIDI emission. When a bidirectional stream is removed, current flow-control level is checked. If needed, a MAX_STREAMS_BIDI frame is generated and inserted in a new list in the QCS instance. The new frames will be emitted at the start of qc_send(). This has no impact on the current MAX_STREAMS_BIDI behavior. However, this mechanism is more flexible and will allow to implement quickly MAX_STREAM_DATA/MAX_DATA emission.
